Chelsea are ready to trigger Atletico Madrid striker Diego Costa’s release clause according to Spanish source Stamford Bridge boss Jose Mourinho is looking to bring in a prolific forward to lead his attack and is ready to fork out the €38m (£31m) it would take to land the 25 year old, who has been called up by Spain for their upcoming friendly with Italy.
