Diego Costa insists he will not return to London to train with the Chelsea squad, but appears to be keeping fit in Blues colours in Brazil.
The 28-year-old striker pleaded with Chelsea to lower their asking price for him in order to complete a move to former club Atletico Madrid on Friday.
Chelsea manager Antonio Conte laughed off Costa's latest outburst against the club, though, insisting the forward is "the past".
But Costa is clearly keeping ties to Chelsea, even if it is only in his choice of training kit.

Diego Costa's stand-off with Chelsea continues - 5,000 miles apart and light-years away from any agreement
The Spain international took to Instagram to prove his fitness as he maintains his stay of isolation in his country of birth, Brazil, and while he may not have the Blues in his heart, he seems to have them on his shorts.
Whether Costa intended any message by wearing the outfit remains unclear, but he may have just been caught short.
