Mikael Forssell is backing Birmingham City teammate Liam Ridgewell not to be rattled by Aston Villa's fans in this weekend's derby.
"Liam is a top man in every way and has the mental strength to handle this situation.
"Everyone who plays against their old team wants to prove a point. I do not think scoring an own goal against Villa when we played them at St Andrews affected him in any way.
"It is a big occasion for him and all of us but it is about being consistent on the day."
