Career
Warner was player-manager at Bowers & Pitsea. Born in Paddington, London, Warner was spotted by Colchester United during a friendly against his then-club Burnham Ramblers. Still on non-contract terms, Colchester wanted to sign Warner permanently and on a full-time basis, but could not offer the security or financially compete with the combination of his salary from Ford and payments from semi-professional football.
He returned to non-league football with Heybridge Swifts for the 1989-1990 season, but returned to Colchester in December 1989 after Steve Foley, who had taken over as caretaker manager, convinced Warner to return.
In this time, he made two further appearances for the U"s, playing his final game for the club on 5 January 1990 in a 1–0 defeat at Layer Road to Stockport County. With Mick Mills taking the Colchester manager role, Warner was told that he could leave, as he subsequently joined Dagenham.
He later played for Collier Row and was player-manager at Bowers & Pitsea. Warner made 17 Football League appearances and scored a total of three goals in the professional leagues.
