John Francis O'Shea (; born 30 April 1981) is an Irish professional football coach and former player who is currently assistant manager of the Republic of Ireland men's national team. He was known for his versatility in playing several defensive and midfield positions on either side of the pitch or the centre. With 14 winners' medals, he is one of the most decorated Irish footballers of all time; only Denis Irwin, Roy Keane, Steve Heighway and Ronnie Whelan have accrued more honours.
Born in Waterford and growing up in Ferrybank, O'Shea joined Manchester United when he was 17. He spent loan spells at AFC Bournemouth and Royal Antwerp before establishing himself in the Manchester United first team, going on to make 393 appearances and scoring 15 times in all competitions across 12 seasons. He won five Premier League titles, one FA Cup, two Football League Cups, four FA Community Shields, the FIFA Club World Cup and the UEFA Champions League with the club. He joined Sunderland in July 2011. Having played 256 times for the Wearside club and scoring four goals, he signed for Championship side Reading in July 2018. Retiring in May 2019, he joined that club's coaching staff that summer, before leaving in the summer of 2021. He then coached at Stoke City and Birmingham City.
O'Shea made his Republic of Ireland debut in 2001 against Croatia and made 118 appearances for his national team over the next 17 years, scoring three goals, his first in 2003 against Australia. He was part of the team that controversially lost to France in a play-off for the 2010 FIFA World Cup and went on to play in UEFA Euro 2012 and UEFA 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 the Manchester United academy, O'Shea played for Ferrybank AFC and Waterford Bohemians. He signed professional forms at the age of 17 and made his professional debut on 13 October 1999 against Aston Villa at Villa Park in a 3–0 Football League Cup defeat.
In January 2000, O'Shea was loaned to AFC Bournemouth in the Football League Second Division. He played 11 total games for the Cherries and scored once in the third minute of a 3–1 loss at Millwall on 19 February. After a loan to Belgian side Royal Antwerp, he returned to Manchester and began to feature in the United first team in the 2002–03 season, demonstrating versatility by playing at left-back, right-back, centre-back and central midfield during the successful 2002–03 Premier League campaign.
In 2003–04, United were without Rio 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 the FA Cup final where they triumphed 3–0 over Millwall.
He displayed indifferent form in the 2004–05 season and was linked with a move away from Manchester, with Newcastle United and Liverpool being linked with the Irishman. One of the highlights of Manchester United's otherwise slightly disappointing season was the 4–2 away victory against Arsenal, in which O'Shea scored the fourth goal by chipping Arsenal goalkeeper Manuel Almunia from the edge of the 18-yard box.
An injury to Gary Neville in the 2005–06 season also gave O'Shea more first-team opportunities. He was criticised for his lacklustre performances that season, and was reportedly one of the players lambasted by United veteran Roy Keane in a controversial interview on the club's MUTV channel.
On 4 February 2007, during a league game against Tottenham Hotspur, O'Shea deputised for Edwin 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 teammate Robbie 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.
A month later, he won over many United fans by scoring a stoppage-time winner against Liverpool at Anfield for United in the league, having come on as a substitute for Wayne Rooney. This goal was important in United going on to regain the Premier League trophy for the 2006–07 season. He also rescued his team against Everton in one of the final games of the season, when he bundled the ball into the net after Everton goalkeeper Iain Turner fumbled a Ryan Giggs corner. United went on to win 4–2. This was perhaps an even more decisive goal, as Bolton Wanderers were drawing with Chelsea 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 to Portsmouth 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 the 2006–07 season.
During the 2007–08 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. 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 a Premier League and Champions League double. O'Shea captained his club for the first time during a 2–0 home defeat to Coventry City in the League Cup Fourth Round.
Throughout the 2008–09 season, O'Shea became a regular within the team, deputising at right-back because of injuries to Gary Neville and Wes Brown. On 20 January 2009, O'Shea scored his first goal of the season against Derby County in the second leg of the League Cup semi-final. O'Shea then started the 2009 Football League Cup final, before being replaced by Nemanja Vidić on 76 minutes, United won the game 4–1 on penalties. On 29 April 2009, O'Shea scored the only goal of the game in the first leg of the Champions League semi-final against Arsenal, this set United up to go on and win in the second leg by 4–1 on aggregate. O'Shea started and played the full 90 minutes in the 2009 Champions League final 2–0 loss to Barcelona, and by many accounts was one of United's better performers on the night. Sir Alex Ferguson had promised O'Shea, who was an unused substitute in the 2008 Champions League final, a starting place in the 2009 final for his contribution to the team that season.
O'Shea captained United for the second time against Birmingham City in their first game of the 2009–10 Premier League season. On his 350th appearance he scored his first league goal in over two years against Stoke City on 29 September 2009, a header in a 2–0 win. He captained the team for the third time in the second leg of United's 2010–11 UEFA Champions League semi-final victory over Schalke 04, but was not named in the squad for the final. O'Shea made 393 total appearances for Manchester United.
On 7 July 2011, O'Shea signed a four-year contract with Sunderland, managed by former Manchester United captain Steve Bruce, who paid Manchester United an undisclosed fee for O'Shea. In his first appearance for Sunderland, a friendly against Arminia Bielefeld, O'Shea picked up a hamstring injury, ruling him out for the rest of pre-season and the start of the 2011–12 campaign. O'Shea made his first competitive appearance for Sunderland on 27 August 2011 in a goalless draw against Swansea.
O'Shea scored his first Sunderland goal at the Stadium of Light in the 2012–13 season in a 2–1 loss to Tottenham Hotspur.
At the end of the 2016–17 season, which ended in Sunderland's relegation, O'Shea's contract had initially expired. However, the Irishman agreed to sign a one-year contract lasting until July 2018.
O'Shea scored his first club goal for more than four years to help Sunderland clinch a 4–1 away win over Derby County to move off the bottom of the Championship table on 30 March 2018. At the end of the season, O'Shea suffered a second consecutive relegation with Sunderland as the team finished in last place.
