Ever Banega has apologised to Atletico Madrid teammates after his dismissal against Villarreal on Sunday.
Banega, on-loan from Valencia, has been forgiven by coach Javier Aguirre, who said: "He is young, is a good guy, a good team player and a great footballer. I have been pleasantly surprised by his play.
"He is young and will learn from his mistakes, like all of us in this business."
