O'Shea made his Republic of Ireland debut in 2001 againstCroatia and made118 appearances for his national team over the next 17 years, scoring three goals, his first in 2003 againstAustralia. He was part of the team thatcontroversially lost to France in a play-off for the2010 FIFA World Cup and went on to play inUEFA Euro 2012 andUEFA Euro 2016. He then served as assistant manager on the under-21 and senior teams, as well as interim manager of the latter in 2024.
Before joining theManchester United academy, O'Shea played for Ferrybank AFC and Waterford Bohemians.[6] He signed professional forms at the age of 17 and made his professional debut on 13 October 1999 againstAston Villa atVilla Park in a 3–0Football League Cup defeat.[7]
In January 2000, O'Shea was loaned toAFC Bournemouth in theFootball League Second Division. He played 11 total games for the Cherries and scored once in the third minute of a 3–1 loss atMillwall on 19 February.[8][9] After a loan to Belgian sideRoyal Antwerp, he returned to Manchester and began to feature in the United first team in the2002–03 season, demonstrating versatility by playing at left-back, right-back, centre-back and central midfield during the successful2002–03 Premier League campaign.[7]
In2003–04, United were withoutRio Ferdinand after he began a suspension for missing a drugs test in January, and O'Shea took over from Ferdinand in central defence, helping United reach theFA Cup final where they triumphed 3–0 over Millwall.[7]
He displayed indifferent form in the2004–05 season and was linked with a move away from Manchester, withNewcastle United andLiverpool being linked with the Irishman.[10] One of the highlights of Manchester United's otherwise slightly disappointing season was the 4–2 away victory againstArsenal, in which O'Shea scored the fourth goal by chipping Arsenal goalkeeperManuel Almunia from the edge of the 18-yard box.[11]
An injury toGary Neville in the2005–06 season also gave O'Shea more first-team opportunities.[10] He was criticised for his lacklustre performances that season, and was reportedly one of the players lambasted by United veteranRoy Keane in a controversial interview on the club'sMUTV channel.[10]
On 4 February 2007, during a league game againstTottenham Hotspur, O'Shea deputised forEdwin van der Sar in goal after Van der Sar was taken off the pitch for a broken nose, while Manchester United had already used all three substitutes. During this time, he denied his Republic of Ireland teammateRobbie Keane a goal with a save a few minutes before full-time. Following this incident, United fans chanted"Ireland's number one" in O'Shea's honour.[12]
A month later, he won over many United fans by scoring a stoppage-time winner against Liverpool atAnfield for United in the league, having come on as a substitute forWayne Rooney.[13] This goal was important in United going on to regain the Premier League trophy for the2006–07 season.[7] He also rescued his team against Everton in one of the final games of the season, when he bundled the ball into the net afterEverton goalkeeperIain Turner fumbled aRyan Giggs corner. United went on to win 4–2.[14] This was perhaps an even more decisive goal, asBolton Wanderers were drawing withChelsea at the same time and defeat would have let Chelsea back into the title race. He scored another goal from close range, in a 2–1 defeat away toPortsmouth that season, this goal came during an injury-hit part of the season, where O'Shea, as a versatile player, was required to play at full-back. O'Shea had a shooting accuracy of 100% and scored with 80% of his shots in the2006–07 season.[15]
During the2007–08 season, Manchester United used O'Shea as an emergency striker due to injury problems. His use as a striker gave him the distinction of having played in every position for Manchester United.[10] In November 2007, O'Shea extended his contract at Manchester United, to keep him at the club until 2012. Throughout the 2007–08 season, O'Shea came off the bench several times as United won aPremier League and Champions League double.

On 20 January 2009, O'Shea scored his first goal of the season againstDerby County in the second leg of the League Cup semi-final.[17] O'Shea then started the2009 Football League Cup final, before being replaced byNemanja Vidić on 76 minutes, United won the game 4–1 onpenalties.[18] On 29 April 2009, O'Shea scored the only goal of the game in the first leg of the Champions League semi-final againstArsenal, this set United up to go on and win in the second leg by 4–1 onaggregate.[19] O'Shea started and played the full 90 minutes in the2009 Champions League final 2–0 loss toBarcelona, and by many accounts was one of United's better performers on the night.[20][21][22]Sir Alex Ferguson had promised O'Shea, who was an unused substitute in the2008 Champions League final, a starting place in the 2009 final for his contribution to the team that season.[23]
O'Shea captained United for the second time againstBirmingham City in their first game of the2009–10 Premier League season.[24] On his 350th appearance he scored his first league goal in over two years againstStoke City on 29 September 2009, a header in a 2–0 win.[25] He captained the team for the third time in the second leg of United's2010–11 UEFA Champions League semi-final victory overSchalke 04,[26] but was not named in the squad forthe final.[27] O'Shea made 393 total appearances for Manchester United.[28]

On 1 April 2009, in the game againstItaly, he was elbowed in the forehead byGiampaolo Pazzini, who earned the record for the fastest sending off in Italian football history. After receiving treatment for the bleeding, O'Shea continued playing all 90 minutes.[44]
O'Shea was scheduled to faceSpain on 11 June 2013 atYankee Stadium in New York, but was ruled out of the game over the sudden death of his uncle Jimmy O'Leary.[47] On 14 October 2014, on his100th cap, O'Shea scored the equalising goal with the last kick of the match, in a 1–1 draw againstGermany atGelsenkirchen, in aUEFA Euro 2016 qualifying match.[48] In the final qualifier, a 2–1 defeat away toPoland on 11 October 2015, he was sent off for a foul onRobert Lewandowski and thus missed the first leg of the Republic's play-off.[49]
