In 1999 Sifakis was transferred to OFI Crete where he played with the B squad of OFI until 2002. In 2002 he signed his first professional contract with the club. He played for OFI until 2007 and participated in 112 matches in the Greek championship and cup.
In 2007 the team Olympiacos made an offer for Sifakis, which was accepted by OFI, and he played as a replacement of the national goalkeeper Antonis Nikopolidis. During the season 2007–2008 his team won the Greek championship, the Greek Cup and the Greek Super Cup. And then he continued to be the replacement.
In 2008 Aris made an offer to OFI and Sifakis was transferred to the club. During the season 2008–2009 Sifakis participated in 27 league and cup matches. He participated in all league games of the 2009–2010 season. In the season 2009–2010 he participated with Aris in the final of Greek Cup, losing against Panathinaikos by 1–0. His reaction in the goal, a long distance shot by Leto, was very slow and his performance is questionable. In the season 2010–2011 he passed the group stage of the Europa League with Aris and were then eliminated by Manchester City of Roberto Mancini, at Round of 32 of the competition. In the following season (2011–2012) he had some medical problems that kept him away from some Aris and national squad's matches. In April 2013 Sifakis demands through his lawyers 988.000 euros from the almost bunkrupt Aris, although his unpaid wages are 188.000.
Newly promoted Jupiler Pro League side R. Charleroi SC are set to sign Michalis Sifakis on a free transfer after the Greek ‘keeper severed ties with Aris at the end of last season. Part of Greece’s UEFA EURO 2012 contingent this past summer, Sifakis replaced Kostas Chalkias midway through Greece’s Group A clash with the Czech Republic and carried the mantle for the national team until Greece were eliminated by Germany in the quarter-finals. Sifakis should have plenty of competition at the club as other ‘keepers in the squad include Parfait Mandanda, the brother of Marseille and France shot-stopper Steve Mandanda. Failing to sign anywhere all summer long, Greece manager Fernando Santos forced to leave Sifakis, as well as other players yet to sign with a club, out of the Greece squad for the recent World Cup Qualifiers against Latvia and Lithuania.
In the summer 2013 Sifakis returned to Greece by signing a 1-year contract with Atromitos. In his first interview as a member of the club he stated that “Atromitos is one of the few teams for which I would have returned to Greece and it is true that only a few days ago I wasn’t even considering it”. Furthermore, “The fact that Atromitos is in a phase of development is something which I am very pleased with, especially at a time when everything in our country is going in the other direction.”  He made his debut at 17 August against a draw 2-2 with Ergotelis. On May 27, 2014 Atromitos, after a year with the club, announced the end of his contract.
In 2004 Sifakis was called for the Greece national under-21 football team. He played 15 games with the U21 selection.
In 2009 Greece’s national team coach, Otto Rehhagel, invited Sifakis to help the national team qualify for the South Africa 2010 FIFA World Cup. On 14 October he contributed to his team's victory against Luxembourg. He was also part of the squad for the final tournament.
Following an injury to regular goalkeeper Kostas Chalkias in Greece' second game of Euro 2012, against the Czech Republic, Sifakis was substituted into the game to replace him and he remained the starting goalkeeper for the rest of the tournament, as Greece reached the Quarter finals of the competition.
In 2009 the Greek Professional Players Association honored Sifakis with the Fair Play award for his professionalism and ethos, due to his calm and non-violent reaction to a confrontation with a fan in the opening game of the 2009–2010 Greek season away at Iraklis. During the match, Sifakis was approached by an Iraklis fan who had run onto the pitch and began to verbally abuse him. Sifakis did not react and the stewards eventually intervened, removing the fan from the pitch. He has been awarded from PSAP as the best goalkeeper in Superleague in the years 2010 and 2011.
