Chelsea manager Jose Mourinho has proclaimed Diego Costa is "happy" with life at Stamford Bridge despite a string of outbursts and recent controversies that might suggest otherwise.
Responding to a recent interview former Atletico Madrid hitman Costa gave to Spanish radio station Onda Cero, where he suggested a return to the Vicente Calderon may be possible, Mourinho stated, per the Guardian's Simon Burnton:
He never said he’d like to go back, he said that in football you never know. Atletico is a great club, Madrid is a great city, La Liga is a great league, so why shouldn’t a player, 27 years old, think that in football it is possible to be back?
