Atletico Madrid A fee of around 60 million euros is being discussed with Chelsea

Chelsea have finally agreed to enter into talks with Atletico Madrid over the sale of Diego Costa, now that the player is ready to return to Europe.

Until now the London-based team had been refusing to negotiate, instead insisting that the unwanted striker had to first return to England after three months of holiday in Brazil to train with the Blues' reserves.

Costa, however, was refusing to come back until Chelsea altered their stance and agreed to enter into talks with Los Rojiblancos, something his agent has communicated to the club.

As such, Chelsea have now been convinced and a deal for the 28-year-old to leave Stamford Bridge should be finalised this week, assuming all goes to plan.

A fee of around 60 million euros is being discussed, which would make Costa the most expensive signing in Atleti history - although it remains to be seen how much of that amount would be guaranteed and how much would be dependent upon performance-related add-ons.
