* Senior club appearances and goals counted for the domestic league only and correct as of 7 May 2016.
After playing amateur football with Iraklis Ampelokipi, Konstantopoulos signed his first professional contract with Kalamata in 1996; he would go on to make 12 appearances in six years for the club, with a spell at Egaleo yielding three further appearances between 2001 and 2002. He moved to Portuguese side Farense after this, before joining Hartlepool United in October 2003. After making 117 league appearances for Hartlepool, Konstantopoulos opted to switch to Coventry City in 2007. However, he was unable to hold down a first team place, and, after loan spells with Nottingham Forest, Swansea City (twice) and Cardiff City between 2008 and 2009, Konstantopoulos was released in 2010 having made 31 league appearances for Coventry. He returned to Greece, spending a successful season with Kerkyra before switching to AEK Athens for the next two seasons. Following AEK's relegation, he was released at the end of his contract, and joined current club Middlesbrough in August 2013.
Konstantopoulos began his professional career with Kalamata in 1996, having previously been playing amateur football for Iraklis Ampelokipi that year. After making seven appearances in four seasons, he spent just over a season with Egaleo from 2001 to 2001, where he made three appearances. He then returned to Kalamata, and made another five appearances the following season. Prior to moving to England, he had been playing in Portugal for SC Farense.
Konstantopoulos spent the majority of his first season playing for Hartlepool’s reserve team and as a substitute. In the following 2004-05 season, Konstantopoulos finally made his début in the 2–1 League Cup win over Macclesfield Town on 24 August 2004. Konstantopoulos then made his league début in the 2–1 win against Colchester United six days later. Although still second-choice to Jim Provett at that point, he would become number one from the end of October, going on to make a total of 37 appearances that year. He was part of the Hartlepool United side that reached the fourth round of the FA Cup in 2005, and he kept 25 clean sheets during Hartlepool's 2005-06 campaign.
Konstantopoulos signed for Coventry City on 30 June 2007, after he rejected a new contract offer from Hartlepool. He made his début in Coventry's first match of the season, which was a 4–1 victory over Barnsley. Although a regular starter for Coventry for the first half of the season, the arrival of Kasper Schmeichel pushed him to third choice (behind Andy Marshall), and Konstantopoulos made his 23rd, and last, appearance of the season on 9 February 2008, in a 1–0 defeat to Millwall.
On 24 March 2008 Konstantopoulos signed for Nottingham Forest on loan until the end of the 2007–08 season. He then ruptured his Achilles tendon on his first day of training at The City Ground.
On 24 October 2008, Konstantopoulos signed for Swansea City on a one-month emergency loan deal, after Swansea's first choice keeper Dorus de Vries suffered a double fracture to his jaw against Queens Park Rangers. He made his Swansea début against Doncaster Rovers on 1 November, saving a penalty late in the match. He extended his loan spell by a month later in November, having made two further appearances. His form for Swansea led to manager Roberto Martinez stating that he wished to keep Konstantopoulos permanently in December. After one further appearance, he briefly returned to Coventry on 2 January 2009 after being recalled due to Coventry's injury problems, before rejoining Swansea on loan four days later until the end of the month. Although Coventry and Swansea agreed a deal that would see Konstantopoulos remain in Wales until the end of the season, issues with the paperwork meant that the Football League refused to allow the extension. He thus returned to Coventry having made five appearances for Swansea in total.
Three days after returning to Coventry, Konstantopoulos was again loaned out, this time to Swansea's local rivals Cardiff City until the end of the season as cover for Finland international Peter Enckelman who was ruled out for up to two months after undergoing knee surgery. With second choice goalkeeper Tom Heaton also being ruled out through injury, Konstantopoulos was handed his debut on 22 February against Wolverhampton Wanderers, a match which ended in a 2–2 draw after Konstantopoulos scored an own goal after dropping a cross from Wolves midfielder Kyel Reid into his own net. Konstantopoulos remained in goal for the following games, but made another error in a 2–0 defeat to Norwich City, when he failed to clear a long pass and was tackled by Dave Mooney to concede the first goal of the game. After Konstantopoulos suffered a foot injury in March, Cardiff manager Dave Jones signed Stuart Taylor on loan from Aston Villa; although Konstantopoulos remained with Cardiff for the rest of the season, he did not play again for the club, and he returned to Coventry at the end of the season having made a total of six appearances.
Return to Coventry City
Konstantopoulos remained with Coventry City for the start of the 2009–10 season, and made his first appearance in a year for the club in the 1–0 League Cup defeat to Hartlepool on 12 August 2009. Following an injury to first choice goalkeeper Keiren Westwood during a match against West Brom on 24 October, Konstantopoulos was brought on as a substitute and helped the club to their first clean sheet in eleven games. Although stating an intention to fight for a first team place, he made just two more appearances before Westwood returned to the team on 21 November. His next appearance came in a 1–1 draw with Portsmouth in the FA Cup on 2 January 2010; although he drew praise from BBC Sport for his performance in this match, it would also prove to be his last game for Coventry. He was released at the end of the season after his contract expired, having made 27 appearances for the club.
After seven years abroad, Konstantopoulos returned to the Greek Super League with Kerkyra. He made his début in Kerkyra's opening game of the season, which was a 2-1 victory against AEK Athens at the Panpeloponnesian Stadium on 29 August. His good form resulted in him being called up to the Greek national football team by coach Fernando Santos, and Konstantopoulos made his senior international début in the 3-1 win against Malta in June 2011. He finished the season having made 30 appearances for Kerkyra.
On 13 July 2011, Konstantopoulos signed a two-year deal with AEK Athens. He suffered a spinal cord injury in a Europa League match against FC Dinamo Tbilisi on 25 August; although able to play in AEK's next Europa League match on 15 September, which was against RSC Anderlecht, he was forced to undergo surgery two weeks later. Konstantopoulos started the season as second-choice behind Giannis Arabatzis in the Super League, but became number one in March. He spent the 2012–13 season as AEK's primary goalkeeper, but after making 24 appearances that season, and 39 league appearances in total, he was released following AEK's relegation.
On 16 August 2013, Konstantopoulos signed a short-term deal with Middlesbrough until January 2014, which was later extended to the end of the season. He had to wait for January's FA Cup defeat to Hull City on 4 January 2014 to make his debut, with Shay Given having joined on loan when first-choice Jason Steele injured his ankle, conceding two goals in the process. He then made his full league debut against Ipswich Town on 8 March 2014 in a 2-0 victory. After Given returned to Aston Villa, Aitor Karanka opted to use Konstantopoulos as his number one goalkeeper, ahead of Steele and Tomas Mejias, and Middlesbrough opened contract talks with Konstantopoulos in April 2014. On 1 May 2014, Konstantopoulos signed a new one-year contract with Middlesbrough after making 13 appearances. He remained number one for the 2014–15 season, and was described by Sky Sports as being "instrumental" to Middlesbrough's form at the end of 2014.
On 19 January 2015 Middlesbrough head coach Aitor Karanka claimed that Konstantopoulos was the "perfect" squad member after the 2-0 win against Huddersfield Town, after conceding 12 goals in 23 matches and keeping 13 clean sheets. Middlesbrough had let in 17 goals in 26 matches; the fewest in the Championship. Konstantopoulos extended his contract with Middlesbrough in February 2015, although the terms were undisclosed. He emerged as Middlesbrough's first-choice keeper for 2014/15, despite the permanent arrival of Mejias from Real Madrid.
On 8 May 2015 in the Championship play-offs, Middlesbrough played Brentford and came away with a 2-1 win, with Fernando Amorebieta scoring in injury time. The came away with a win and a one-goal advantage. Alan Judge's booming shot hit the cross-bar out of nowhere, and replays confirmed Konstantopoulos' fingertips stopped the ball from going in. On 25 May 2015, Konstantopoulos played in the 2015 Championship play-off final, where Norwich City claimed an instant return to the Premier League as they recorded a 2-0 play-off final victory against Middlesbrough at Wembley.  On 17 December 2015, Middlesbrough head coach Aitor Karanka said that Dimi has played a big part of that solidity and the first place of the club so far in the Championship, and with the keeper having made 20 league appearances this season, a clause in his contract that means his stay on Teesside is renewed for another year. Dimi’s strong performances have meant the Greek has seized his place as Boro’s number one and Karanka has hailed the keeper as an example to others.   In 24 league matches this season he has kept 15 clean sheets and eight in a row. Additionally he succeeded to have 9 clean sheets in home games and in 13 home games so far had only received 2 goals.  On 18 February 2016, on a report written by Jonathon Taylor, Konstantopoulos having conceded only 16 goals in 30 league games to date, he is on course to become the most successful goalkeeper in more than 100 Boro campaigns. Dimi has kept 17 clean sheets already this season, four more than Bayern Munich No 1 Manuel Neuer and five more than Arsenal stopper Petr Cech. He was part of the record-breaking Boro rearguard who racked up nine consecutive league clean sheets, smashing a 30-year club milestone.  On 29 April 2016, in a 2-2 away game against Birmingham reached 100 appearances with the jersey of Middlesbrough.  On 7 May 2016, in the very last matchday following their 1-1 draw with rivals Brighton he celebrated with the club, after seven long years in the Championship, the return to England's top flight.   Furthermore, he kept 22 clean sheets in this season setting a new record for the club.  On summer 2016, the coming of Victor Valdes and Brad Guzan created an extra pressure to Dimi for the first goalie of the new season. Guzan is the second international keeper the head coach Aitor Karanka has brought to the Premier League new boys after Barcelona legend Victor Valdes. Despite his advancing years – he will be 38 later this year – and the fact he has no Premier experience, the majority of pundits and supporters feel he warranted a chance in the top flight.  
On 17 November 2010, Dimi Konstantopoulos has received a call up to the Greek national squad for a game with Austria. On 6 April 2011, he made his only appearance with the national squad so far against Malta in UEFA Euro 2012 qualification.
