Jose Mourinho wants Chelsea to buy a big-name striker in January - with Atletico Madrid’s Diego Costa on his wish-list.

Manager Mourinho believes the Blues need to add a new forward in the winter transfer window to strengthen their title challenge.

Mourinho is hopeful Roman Abramovich will back him after they missed out on Wayne Rooney in the summer and none of their forwards have established themselves as No1.

They are looking around for options and Mourinho fancies Costa who is set to represent Spain at next year's World Cup despite previously playing two friendlies for Brazil.

Liverpool were keen in the summer but Costa stayed and renegotiated terms and Atletico are now likely to demand over £35million for him.

Chelsea are unlikely to go to that figure - especially with Romelu Lukaku to come back next summer after a season's loan at Everton.
