Atletico Madrid fans do not want Joao Felix to return from Barcelona.
Felix is on-loan at Barca and scored the winner against his parent club on Sunday.
Alberto Garcia, who is the spokesperson for the International Union of Supporters Clubs of Atletico Madrid, declared in a statement: “Now it turns out that he has been a Barcelona fan since he was a child and celebrates goals as if there was a title at stake. It was his second goal in La Liga, it's not like he's having a great season.
“It is ungrateful and disrespectful to a fan base that has been his and has treated him well.
"He has generated a hostile atmosphere for the Metropolitano and we do not want to see him again with the Atletico Madrid shirt on. He doesn't deserve (the club) and he hasn't understood this club or these fans."
