Griezmann has a 100-million euro (US$119 million) release clause in his contract and Spanish media say that Barcelona is ready to pay it. "We have a good relationship with them".
RMC report tonight that Barcelona intend to sign French global attacker Antoine Griezmann this summer, but only after the 1st of July, when a clause in his Atletico Madrid contract comes into effect which sees his release clause drop from €200m to €100m.
Griezmann signed a new contract shortly after his failed move to Manchester United last summer, and a stipulation in that deal will see his release clause halved from €200 million (£175m) to €100m (£87m) from July 1.
Barca have emerged as favourites to sign the France global and are reportedly willing to meet his £88m release clause, with club president Josep Maria Bartomeu revealing earlier this week that he has already spoken to the player's agent.
Griezmann has been heavily linked with a move to the Nou Camp, with speculation in Spain that a 100million euros (£88million) switch will be completed this summer.
Atletico are not pleased with the recent developments as club chief executive Miguel Angel Gil Marin reiterated that their star player is not for sale.
"We do not speak about players from other teams", Bartomeu said.More news: Wenger Advises Next Arsenal Boss What To Do To Win Title

Atletico recently hit out at Barcelona over their pursuit of Griezmann, especially ahead of their crucial Europa League final with Marseille on May 16.
"He's a great player, I have no doubt about that".
But it seems that the Atletico Madrid is not very happy with it as they have grown "fed up with Barcelona's attitude" as the Catalans continue to openly court Griezmann. "Now we do not think about that, we think about being able to be European champions, in which we have a great, ideal coach, and who will be with us many more years".
"I think we have to respect what we have here and also our opponents".
Atletico Madrid president Enrique Cerezo admits his club is "fighting" to reduce its debt and warned supporters about potential player sales.
The French star looks set to leave Atletico Madrid this summer, something he backed away from doing previous year due to a transfer embargo on the Spanish outfit - which meant they could not replace him. "You can not talk about players who play at other clubs".
