Atletico Madrid are protesting superstar striker Antoine Griezmann's transfer to Barcelona on the grounds of insufficient payment.
According to Robbie Dunne of AS.com, Atletico Madrid released the following statement on the matter:
"The amount deposited is insufficient to pay his release clause because it's obvious that the agreement between the club and Barcelona was done before his fee dropped from €200 to €120 million.
"Atletico Madrid understand that the contract was broken before the end of last season, on the basis of the facts, actions and statements of the player and the club has therefore started the proceedings it considers opportune to defend its legitimate rights and interests.
