Ashfield Boys' High School. He started his career when he joined St Andrews, once scoring 54 goals in one season. He signed as a trainee with
Leeds United, in 1998, but never made the league side and was loaned out to
AFC Bournemouth in 2001.

Luton Town Feeney moved on to
Luton Town for £150,000. He did not have a great start to his Luton career, scoring only 6 goals in 30 starts and 18 substitute appearances in the

Cardiff City At the end of his loan spell at
Cardiff he agreed a three-year deal with the club, but he failed to find the net in a competitive game, his only goal coming in a pre-season friendly against Dutch side
FC Twente. However, considering the deal he had just signed it was perhaps surprising when he was loaned to
Swansea City for four months from 21 August 2007
Swansea City He scored his first goal for Swansea on 2 October, in a 2–1 win over
Swindon Town and began to establish himself in the side, scoring 5 goals in ten matches, but on 15 December, while playing for Swansea in a match against
Southend United he sustained injury to an ankle ligament after a heavy tackle by
Lewis Hunt. His injury ended his opportunity of a permanent switch to Swansea, who had already held talks with Cardiff about a permanent deal. Warren's grandfather,
Jim Feeney had also played for Swansea in the 1940s, and also won international caps for Northern Ireland – they were the first grandfather/grandson to have played for the Swans. In January 2008, Swansea manager
Roberto Martínez put an end to the transfer speculation by stating that "it is going to be very, very difficult to agree something over Warren" meaning that he will not be moving to them in January but Martínez also mentioned that a summer move would not be out of the question. league 1 winner with swansea 2007
Cardiff City Back at Cardiff, he returned from the injury in March 2008, coming on as a 90th-minute substitute for

West Bromwich Albion which ended his season.
Dundee United In July 2008, Feeney joined fellow Cardiff City player
Willo Flood on loan at
Scottish Premier League side

Raith Rovers at
Stark's Park, although he did not score his first competitive goal until November. He went on to score 6 league goals for the Scottish club by the end of the season, only for a groin injury to put an end to his loan spell.
Return to Cardiff After returning to Cardiff again his injury woes continued, and in July 2009 it was reported on the BBC website that Feeney would miss the start of the 2009–10 season as he would undergo hip surgery, he would also miss vital
World Cup games for
Northern Ireland. This problem was believed to have come to light during a medical with
League One side
Leeds United, the club where he started his career, but after failing this medical the move was called off. He returned to action for Cardiff on 17 October 2009, when came on as a substitute for
Chris Burke during a 1–1 draw with
Crystal Palace.
