​Atletico Madrid have confirmed that Antoine Griezmann has signed a new deal with the club, increasing his buyout clause, per AS.

The frenchman has signed a new deal that will run until 2020 with a significantly increased buyout clause and higher wages as a reward for last seasons rich form.

The winger scored 22 La Liga goals since moving for Real Sociedad to help Diego Simeone's side qualify for the Champions League. 

Rumours where circulating this summer that Chelsea where launching a move to sign the french international, triggering Atletico to open contract talks with their star man. 

It is reported that the original contract had a buyout clause of €65 million, but that has been significantly increased in the new contract after the player reiterated his desire to stay with the La Liga outfit on several occasions. 

The French international has been capped 15 times, scoring five goals in the process. 

If reports are true and Mourinho is a true admirer of the frenchman, he and Chelsea will now have to break the bank to have any chance of signing the winger. 

A deal seems unlikely because the Chelsea manager has recently insisted he is happy with his three player attack of Loci Remy, Diego Costa and Radamel Falcao. 

Bayern Munich are also said to have been keeping tabs on the progress of the attacker but he now seems certain to remain in Spain this summer.
