Jack Cork

Cork joined the Chelsea youth system up age of nine, and captained both the club's youth and reserve teams. During the 2006–07 season, Cork twice went on loan to League One club AFC Bournemouth. Cork was selected to go on Chelsea's pre-season tour of the United States in summer 2007. He made his first appearance for the first team against Club América on 14 July. He played out-of-position at left back for most of the tour.

Cork spent the 2007–08 season on loan at newly promoted Championship club Scunthorpe United. His first league goals came for Scunthorpe, both against Coventry City; in a 1–1 away draw on 27 November 2007 and in a 2–1 home victory on 1 March 2008. After 35 appearances, despite Scunthorpe's relegation from the Championship, he was voted the club's Player of the Year.

Cork has represented England at many youth levels, making his under-19 debut against the Czech Republic in May 2007. He captained the England U19 squad to make the 2008 UEFA European Under-19 Championship, and was part of the under-21 squad at the 2011 UEFA European Under-21 Championship.

On 21 August 2008, Cork joined Championship club Southampton on loan until 1 January 2009. In January 2009, Cork joined Championship club Watford on loan until the end of the 2008–09 season. He scored his first goal for Watford on 24 January 2009 in a 4–3 victory over Crystal Palace in the fourth round of the FA Cup. Cork signed a new three-year contract with Chelsea on 21 August 2009 and immediately joined Championship club Coventry City on loan until the end of December 2009.

On 1 February 2010, Cork joined Premier League club Burnley on loan until the end of the 2009–10 season. He made his first appearance for Burnley in a 3–0 defeat away to Fulham on his Premier League debut. He then played in a 5–2 defeat against Aston Villa on 21 February 2010 and assisted Burnley's second goal. Cork scored his first goal for Burnley on 9 May 2010 in a 4–2 home win over Tottenham Hotspur, with a diving header to score Burnley's second to turn over a two-goal lead. His father revealed the day before in a local newspaper, the Lancashire Telegraph, that Cork was looking to leave Chelsea in the summer and was willing to drop down into the Championship in order to do so.

On 8 August 2010, Chelsea said that they would allow Cork to leave the club and were looking for offers of around £2 million. On 12 August, Cork re-joined Burnley on loan for the 2010–11 season. Cork scored a last minute winner at home to Derby County on 27 November, taking Burnley into the play-off positions.

On 7 July 2011, Cork signed for newly promoted Championship club Southampton, after they agreed an undisclosed fee with Chelsea. Cork ended the 2011–12 season as the only Southampton player who appeared in every league match, as the club earned promotion to the Premier League as runners-up in the Championship.

On 2 July 2012, Cork was named in Stuart Pearce's 18-man Great Britain squad for the 2012 Summer Olympics. He made his debut on 20 July in a 2–0 loss to Brazil in a pre-tournament friendly, coming on at half-time to replace Daniel Sturridge. He played as a substitute in each of Great Britain's three group matches, and was an unused substitute as the team were knocked out by South Korea in the quarter-final.

Cork missed Southampton's opening fixtures of the 2012–13 Premier League, due to an ankle injury, sustained against Bristol City in a friendly and a League Cup victory over Sheffield Wednesday. On 26 August 2014, he scored his first goal for Southampton in a 2–0 away victory over Millwall in the second round of the League Cup.

He scored his first league goal for the club in a 4–0 home win over Newcastle United on 13 September 2014 and his second and final league goal for the club came in an 8–0 home win over Sunderland on 18 October.

Cork signed for Southampton's Premier League rivals Swansea City on 30 January 2015 on a three-and-a-half-year contract, for a fee "believed to be in the region of £3 million". On 25 April 2015, he scored his first goal for Swansea in a 3–2 away win over Newcastle United.

Over a year after his first goal for the club, on 1 May 2016, he scored his second, with a 20-yard curling shot in a 3–1 home victory over Liverpool. This victory helped secure Swansea's Premier League status for the 2016–17 season.

Cork returned to Premier League club Burnley on 11 July 2017 on a four-year contract, for fee reported to be in the region of £8 million, rising to £10 million with add-ons. He scored his first goal on his return to Burnley in an EFL Cup tie against Blackburn Rovers on 23 August 2017. His first Premier League goal for Burnley came against his former club Swansea City in a 2–0 win on 18 November. That goal ended a run of 43 appearances without a goal for the player.

On 7 November 2017, Cork was called into the England squad for friendly matches against Germany and Brazil. He made his debut on 10 November 2017 as an 86th-minute substitute in a 0–0 draw against Germany at Wembley Stadium.

On 16 August 2018, he scored the winning goal in Burnley's 1–0 victory over İstanbul Başakşehir in the Europa League qualifiers.
