Manchester City won't extend contracts with Martin Petrov, Sylvinho and Benjani next season, the English Premier League club said on Tuesday.

Bulgaria winger Petrov struggled for game time at City with Craig Bellamy, Robinho and Adam Johnson all playing in his position, while he also was plagued by injury problems.

Zimbabwe captain Benjani was another signing by former manager Sven-Goran Eriksson but was sent out on loan to Premier League side Sunderland last season by new coach Roberto Mancini.

Veteran Brazilian left back Sylvinho leaves after just one season at City.
