Atletico Madrid have made a first offer to Chelsea for Diego Costa this week.

Marca says Atletico officials met with Chelsea chief Marina Granovskaia and tabled a concrete offer for the striker.

Atletico have bid €60m for the Spain international and Chelsea are now considering their next move.

For his part, Costa remains in Brazil, though family and members of his entourage have relocated to Madrid in anticipation of negotiations being successful.

Atletico cannot register Costa until January 1 and there are even suggestions FIFA will block him from training with the first team squad until then.
