Atletico Madrid president Enrique Cerezo says he won't have a major issue if Joao Felix kisses the Barcelona badge should he score against them on Sunday.
Felix is on-loan at Barca from Atletico for the season.
Cerezo said: "I always think that football is a spectacle and you have to see the teams with the best players. Of course, Joao Flix is a magnificent player.
"Due to various circumstances, he is not at Atltico.
"I wouldn't be surprised if Joao had a big afternoon, but if not, then it will be the next one."
Cerezo also said of whether Felix will kiss the Barca badge: "Keep in mind that many players kiss the shield, I don't know what's on his mind right now, I haven't spoken to him for two years, but, really, if he kisses the Barcelona shield it's because he feels for Barcelona, if not, he wouldn't kiss it."
