Atletico Madrid have opened talks with Chelsea to re-sign striker Diego Costa.
Madrid are looking to add depth to their attacking options and have money to spend from the sale of Jackson Martinez to China.
It is understood that Chelsea are aware that Costa is unsettled at Stamford Bridge and is wanting a move back to the Spanish capital.
The Blues have already secured the signing of Batshuayi from Marseille and also have a strong interest in Real Madrid forward Alvaro Morata. So, Chelsea could be willing to part ways with Costa if the price is right.
