Birmingham were beaten by Coventry as they missed the chance to draw level with Championship leaders Wolves.The Sky Blues went ahead in the second minute when Scott Dann was left unmarked at a Daniel Fox corner and powered in a shot.Birmingham thought they had equalised late in the game but Scott Sinclair's goal was disallowed for offside.The away side were left fuming but they put in a below-par performance as they rarely looked like equalising.Coventry boss Chris Coleman: "I thought we deserved it today. We created a lot of chances and could have won by more."Birmingham did have their moments but overall I thought we deserved the three points so I am delighted."There was a lot of enthusiasm in our performance and, to a man, I thought we were magnificent. As for promotion, our aim is to finish in the top half."Birmingham manager Alex McLeish: "In the first minute, you want an inspirational tackle or header to get everybody going but that never happened."Instead, we didn't deal with a long ball and they forced a corner."We didn't learn our lesson because they score from the set-piece so it was fairly soft from our point of view. That made us nervous."Coventry: Westwood, Wright, Dann, Turner, Fox, Bell, Gunnarsson, Doyle, McKenzie (Henderson 54), Best (Simpson 88), Morrison (Eastwood 89).
