Antoine Griezmann has urged Joao Felix to not become a disruption at Atletico Madrid.
Felix has upset many fans and Atletico officials after declaring he wants to join Barcelona.
Griezmann said: "In the past I experienced the same situation as Joao, because I went to leave and I had done damage to the club.
"The best thing I could do was shut me up, work and be one more to get into the manager's projects.
"That's the only thing I can say."
