He mainly played for the Gunners' youth and reserve sides; his sole first-team appearance was in a 2–1 League Cup defeat at Highbury at the hands of Ipswich Town on 1 November 2000, coming on as a second-half substitute. In further need of first-team experience he joined Northampton Town on a month's loan on 25 January 2001, making his league début in a goalless draw at home to Peterborough United two days later. He played only one further game for Northampton before returning to Highbury, and although attracting interest from Torquay manager Colin Lee, remained there beyond transfer deadline day. In April 2001 he went to Middlesbrough on trial, but due to an injury crisis at Highbury was recalled by Arsène Wenger. In the summer of 2001 it was clear that he did not fit into Wenger's plans for Arsenal, and was released.

His first appearance for the Shrews came in the 1–1 draw at Mansfield Town on 3 February 2007; he was substituted when Shrewsbury led 1–0. He was released in May 2007, injuries ruling him out of the playoffs and hastening his departure, with an expected move to Milton Keynes Dons on the cards. He did however, make a cameo appearance in the playoff final against Bristol Rovers in the form of being incorrectly credited as Shrewsbury's goalscorer in the Wembley Stadium scoreboard, when in fact it was midfielder Stewart Drummond He had a trial with Bournemouth and on 24 July 2007, but signed for Notts County, in League Two and quickly became a regular in their side, but was released at the end of the season along with seven other players.
