Atletico Madrid have accused Antoine Griezmann and Barcelona of “disrespect” and say the La Liga champions talked to their forward in March.
Atletico say they have rejected Barcelona’s offer and ordered Frenchman Griezmann to report for pre-season.
In a statement, the Madrid club expressed their “strongest repulsion for the behaviour of both, especially Barcelona”.
Griezmann, 28, said in May he would leave Atletico this summer.
Atletico say they have told Griezmann that he is obliged to come in to train with them on Sunday. And they have flatly refused to accept Barcelona’s request to pay his €120m release clause in installments.
The statement also confirmed there was a meeting on Thursday in which Barcelona requested to pay in installments but it added: ‘Obviously the response from Atletico Madrid was negative, understanding both that FC Barcelona and the player have disrespected Atletico Madrid and all its fans.
‘As a result of all this, today, Atletico Madrid has requested the player, his sister as agent of the footballer, and his lawyer, that Antoine Griezmann, in compliance with their contractual obligations with our club, appear next Sunday in the facilities to start the preseason with the rest of his teammates.’
