Jason Koumas (born 25 September 1979) is a Welsh former professional footballer who played as a midfielder for Tranmere Rovers, Cardiff City, West Bromwich Albion and Wigan Athletic, as well as the Wales national team.

[2] Born in Wrexham to an English mother and Greek-Cypriot father, Koumas played for local youth sides during his primary school years, before joining the Liverpool Academy aged nine.

[2] However, he did not sign Youth Training Scheme forms with the club, reportedly due to coaching staff refusing to play him in his preferred central midfield position, instead opting to join Tranmere Rovers.

[4] In August 2002, this potential was spotted by then West Bromwich Albion manager, Gary Megson, who paid Rovers a fee of £2.25 million to secure his services.

On 18 April 2004, Koumas scored a last minute goal in a vital 1–0 win against fellow promotion chasers Sunderland, which essentially sealed Albion's return to the Premier League.

Throughout the remainder of the season, Koumas consistently turned in man-of-the-match winning performances, scoring 13 times in 44 appearances from midfield, including a hattrick away at Luton in a pulsating victory.

Koumas earned himself hero status amongst the Bluebirds faithful as well as the club's Player of the Year award and a place in the Championship's PFA Team of the Season.

[12] Cardiff City then attempted to negotiate a transfer fee for Koumas before the start of the 2006–07 season, however they failed to come to an agreement with West Brom.

[13] His club career was then rejuvenated under new manager Tony Mowbray, becoming a first team regular again and putting in several man of the match performances during the 2006–07 season.

[16] Despite the individual accolades, Koumas was unable to help West Brom achieve promotion following a defeat to Derby in the 2007 Football League Championship play-off final.

[19] The following month he marked his 300th career league appearance by scoring his first goal for his new club, converting an 80th-minute penalty to rescue a 1–1 home draw with Fulham.

[22] Koumas made his second Cardiff City debut in the 4–0 home victory over Doncaster Rovers, coming on as a late substitute for Craig Bellamy.

It was revealed by BBC on 8 July 2013 that Koumas asked to train with former club Tranmere Rovers as he attempted to rebuild his footballing career.
