Troubled midfielder, who failed to make it out of the Spurs Youth team, but went on to have a career in the lower levels of the game, ending up as a striker.
Didn't make it out of the Spurs youth set up and his first stop on being released by Spurs was at Folkestone Invicta, after short spells with Margate and Horsham.
Headed the scoring ranking at Crawley Town in 2004-05, before moving to Canvey Island for a short spell and then onto Eastbourne Borough, for whom he hit 14 goals in their promotion season to the Vauxhall Conference. At the end of the 2008-09 season, Allan moved to Basingstoke Town on loan to return to Eastbourne in March only to be released by the club at the end of the season.
Found a new start at Dartford for the 2009-2010 season, before moving on to Kingstonian in 2011.
