Barcelona’s Antoine Griezmann said former club Atletico Madrid’s angry response to his transfer is “a pity.”
Griezmann joined Barca this week after the Catalans met his 120m euro (£107m) buyout clause.
Atletico complained Barcelona and Griezmann had negotiated the deal before the buy-out price dropped from 200 million euros at the start of July.
“We reached an agreement but finally it changed, it’s like that, you have to accept it,” Griezmann insisted.
Shortly after Griezmann’s move was confirmed, Atletico issued a statement revealing that they had already “begun appropriate procedures” to defend their “rights and legitimate interests”.
Reports in the Spanish media over the weekend claimed Atletico planned to go to governing body Fifa to argue that Barcelona owe them more than the 120 million euros release clause.
