Joshua Christian Kojo King (born 15 January 1992) is a Norwegian professional footballer who plays as a forward or left winger for Ligue 1 club Toulouse and the Norway national team.

[5] While at Vålerenga, King trained with English side Manchester United on multiple occasions, but UEFA rules prevented him from signing a contract with the club until he was 16.

[5] King signed for Manchester United when he turned 16 in January 2008,[7] and made his debut for the under-18 side in a 5–1 home defeat to Sunderland on 29 March 2008.

He returned at the start of April 2009,[19] just in time to play in the run-in to the end of the Under-18 league season, as United finished in second place, 19 points behind winners Manchester City.

At the start of the 2009–10 season, King came on as a substitute for Zoran Tošić in the final of the Lancashire Senior Cup, a 1–0 win over Bolton Wanderers.

[32] King played in seven of Preston's first 12 league games, but suffered an ankle injury at the end of October 2010 that ruled him out for the rest of the loan, and he returned to Manchester United.

[33] After his recovery towards the end of November, King returned to Preston on another loan until 4 January 2011;[34] however, he made just one more appearance for the club before being recalled by Manchester United a few days early.

[37] After his return to Manchester United, King was a regular in the reserve team, playing in 17 of the last 18 games of the season; his only absence came against Arsenal on 28 April 2011.

[45] In recognition of his performances in the second half of the season, King was rewarded with a new two-year contract with Manchester United, keeping him at the club until the summer of 2013.

[48] Borussia confirmed the loan transfer on 22 July 2011, the terms of which were undisclosed by either club, although it was still subject to King passing a medical examination on 1 August.

[51] After just one more substitute appearance and a total of 19 minutes on the field, a recurrence of King's groin injury resulted in his loan spell being terminated early.

[63] In search of first-team football, King was allowed to join Blackburn Rovers on loan until 31 December 2012,[64] with a view to eventually making the move permanent.

Despite competition up front from Jordan Rhodes, Colin Kazim-Richards, Rubén Rochina and Nuno Gomes,[65] he made his debut two days later, coming on as a 55th-minute substitute for Marcus Olsson in a 2–0 defeat at home to Millwall.

[67] After scoring two goals in eight appearances, King's transfer to Blackburn was made permanent as he signed a two-and-a-half-year contract on 2 January 2013, with the option of extending the deal by a further year.

[81] On 9 July 2021, King joined newly promoted Premier League side Watford on a free transfer, a two-year deal with the option of a third.

[90] King replaced Alexander Søderlund as a substitute at half time against Cyprus in Larnaca on 16 October 2012, then won a penalty and scored the last goal in Norway's 3–1 victory.

[93] On 10 October 2014, he scored two goals against Malta in a 3–0 away win in UEFA Euro 2016 qualifying,[94] but was dropped by manager Per-Mathias Høgmo from their play-off against Hungary in place of Veton Berisha, Marcus Pedersen and Alexander Søderlund.
