Atletico Madrid The deal will not be closed before September 1st

Atletico Madrid are still working on the arrival of Diego Costa, although the deal is unlikely to be completed before the transfer window's deadline.

The FIFA-imposed sanction prevents the Rojiblancos from registering new players into their squad until January 1.

For that reason, they could maintain an open dialogue with Chelsea over the striker's transfer even after the window officially closes as there is still no agreement between all of the parties.

Each party has made their position clear but the main problem now is the striker's attitude and his refusal to report back to London from Brazil.

The Blues are taking a stance that even although a great deal of bad blood exists between Costa and coach Antonio Conte, they are under no obligation to sell him and they do not have to facilitate his wish to leave if he does not co-operate.

Both clubs are trying to convince Costa that the best thing for his future is to return to the English capital and attempt to resolve the ugly situation that surrounds him and find a solution to the problem.

Chelsea are determined not to set a precedent by going too easy on a player who has rebelled against the hierarchy in the manner which he has.
