Birmingham forward Quincy Owusu-Abeyie scored on his debut for the club as they beat Wycombe to ease into the second round of the Carling Cup.

Mehdi Nafti had put the Blues ahead with a 20-yard strike before Sebastian Larsson added a second after a one-two with the lively Garry O'Connor.

The Swede then crossed for substitute Cameron Jerome to head home a third.

Owusu-Abeyie rounded off the win when he smashed in from 18 yards with a nonchalant finish.
