Goals from Gary Cahill and Ramires have given Chelsea a 2-1 lead over Bradford City in their FA Cup fourth-round tie at Stamford Bridge this afternoon.

The League One side almost took a shock lead early on when Andrew Davies met a corner from Filipe Morais, but his header was saved by Petr Cech.

However, it was the Blues who went ahead in the 21st minute when Cahill arrived at the near post to flick Oscar's corner into the net.

Chelsea were looking to put the game beyond reach of the visitors and Didier Drogba forced Ben Williams into a couple of saves.

Ramires then doubled the Blues' lead in the 38th minute when he drove forward from the halfway line, before exchanging passes with Mohamed Salah and finishing into the corner.

With four minutes of the first half remaining, Bradford pulled a goal back through Jon Stead, who fired in a powerful strike that beat Cech at his near post.
