Chelsea fans hoping to see Diego Costa again in Stamford Bridge when Chelsea face Atletico Madrid in the Champions League might not like this news.
According to reliable transfer expert Fabrizio Romano, Costa is set to leave Atletico Madrid in January or on a free transfer next summer.
Atletico Madrid are reportedly open to selling Costa in January but should an appropriate offer not come in they will let him leave for free in the summer instead.
