Club career 
Born in Viana do Castelo, Tiago first came to prominence at Sporting de Braga, being cast into the Minho side's starting XI at the age of just 19, and helping with 27 games as it finished in 4th place in 2001, thus qualifying for the UEFA Cup.
In late December 2001, solid displays earned Tiago – and Braga teammates Armando Sá and Ricardo Rocha – a move to league giants Sport Lisboa e Benfica; in his first full season he scored a career-best 13 goals, helping the Reds finish second in the league and, the following year, helped deny F.C. Porto a historic treble by winning the domestic cup.
Tiago signed for Chelsea on 20 July 2004 for a €15 million fee, becoming José Mourinho's sixth signing that season (this included three other Portuguese players). Having missed the first game of the 2004–05 campaign he soon became an important member of his new team, scoring on his away debut against Crystal Palace on 24 August; he also scored a long-range goal in Chelsea's 3–1 win over Manchester United on 10 May 2005, after already having won the Premier League title.
Tiago was a regular for Chelsea that season, having only missed four games in the league. He ended the season successfully as a firm fixture in the Blues' midfield three, making 51 appearances in all competitions and scoring four goals, as the club also added the season's Football League Cup; however, despite his initial success, the following campaign saw the arrival of Ghanaian Michael Essien from Olympique Lyonnais, which limited his first-team chances.
In late August 2005 Tiago signed for Essien's former club on a four-year contract, for a €10.1 million transfer fee. Mourinho later confessed in an interview that letting him go was "a big mistake."
Usually playing in a defensive midfield role alongside Juninho Pernambucano, Mahamadou Diarra and Florent Malouda, Tiago excelled for Lyon, scoring seven goals in 37 appearances. The highlights of his first season in France were a pair of goals against PSV Eindhoven that took Lyon into the quarter-finals in the UEFA Champions League, and the winning goal against Troyes AC on 1 April 2006; the club finished top of Ligue 1, winning a fifth consecutive accolade.
After the departure of Diarra to Real Madrid the following season, Tiago began to play a more significant role in Lyon's midfield with Diarra's replacement, Jérémy Toulalan. He won his second league title and helped L'OL to the domestic league cup final, where it lost to FC Girondins de Bordeaux after a last-minute strike; overall he netted six goals in 40 appearances in his second year.
On 17 June 2007, Lyon president Jean-Michel Aulas confirmed that Tiago's departure from Lyon was imminent with both Juventus F.C. and A.C. Milan reportedly after his signature. He officially signed for the former on 21 June 2007, for a €13 million fee. His performance in the 2007–08 season was criticised, however, as Goal.com describing him as the third biggest flop of the season.
The start of 2008–09 season gave Tiago an opportunity to return to the Premier League in the form of year long loan offer from Everton. Juventus agreed to the deal but Tiago refused their terms, favouring to stay in Italy instead. The negotiations between the player and the club had a violent end when Tiago forcibly locked Juventus president Giovanni Cobolli Gigli inside a toilet stall – the chairman was finally rescued by captain Alessandro Del Piero, more than an hour later; after a difficult first season he eventually established himself in Claudio Ranieri's side but, in November 2008, against Inter Milan, he was stretchered off the pitch with a serious knee injury just several minutes into the match, and was sidelined for almost two months.
Tiago returned to the bench for the January match against S.S. Lazio, but found himself down the pecking order as Cristiano Zanetti, Mohamed Sissoko, and emerging youngster Claudio Marchisio were Ranieri's preferred centre midfield pairing. Following injuries to Sissoko and later Marchisio he was back in the starting XI, but his return was soured by a straight red card in the Derby d'Italia fixture in April (1–1 home draw).
The first half of the 2009–10 season was one to forget for Tiago. With the arrivals of midfielders Diego and Felipe Melo, coupled by his slight dip in form, his appearances were again limited; under Ciro Ferrara he was relegated to the bench once again, only making seven Serie A appearances.
Atlético Madrid 
On 8 January 2010, Tiago joined Atlético Madrid on loan until the end of the season. He scored his first league goal in nearly three years on 21 January, heading home against Celta de Vigo in a 1–1 home draw for the season's Copa del Rey (2–1 aggregate win); gradually, he established himself in the starting lineup ahead of longtime incumbent Raúl García, also reuniting with former Benfica teammate Simão Sabrosa.
After helping the Colchoneros to the domestic cup final – he was cup-tied for the Europa League – a new loan deal was arranged with Juventus. Again, he played in significantly more minutes than García as Atlético finally qualified to the Europa League, and added four goals in La Liga, including a brace against Málaga CF in a 3–0 away win, both goals coming from headers.
On 20 July 2011, Tiago penned a two-year permanent contract with Atlético Madrid. He was again an important part of the team that reached the Europa League final, usually playing as a starter under coach Diego Simeone, who replaced Gregorio Manzano midway through the season; he missed the decisive match in Bucharest however, being sent off in the semifinal's second leg against Valencia CF (1–0 away win, 5–2 on aggregate) after slapping Roberto Soldado.
International career 
Tiago's performances in Portugal's youth teams eventually earned him his senior debut against Scotland in a November 2002 friendly. He went on to seal a regular berth in the squad and was included in the 23-man list for UEFA Euro 2004, although he did not play in the finals.
Moving to France proved crucial in international selection as Tiago's strong form at Lyon afforded him a place in Portugal's well-established midfield. His contributions aided the national team in its quest for qualification for the 2006 FIFA World Cup, and he appeared in five matches in the tournament held in Germany as Portugal reached the semi-finals, losing to France.
Tiago was selected for the squad at the 2010 World Cup in South Africa, replacing Deco in the first game, a 0–0 against Côte d'Ivoire. He took the naturalized Brazilian's place for the following contest, against North Korea in Cape Town on 21 June 2010, and netted twice (including a header) in a 7–0 rout.
After the World Cup, Tiago officially quit the national team citing personal reasons, and also to "make room for opportunities for younger players," ending his international career with 58 caps and three goals.
