Birmingham have completed the signing of Chelsea defender Ben Gordon on a six-month loan deal.

The 21-year-old also has the option to extend his stay at St Andrews until the end of the season if both parties agree.

Gordon is an England Under-20 international, but has yet to make a senior start for the Chelsea first team.

However, he has gained some vital first-team experience during other loan spells with Scunthorpe, Peterborough, Tranmere and Kilmarnock.
