Diego Costa thinks Antoine Griezmann's decision to leave Atletico Madrid and join Barcelona this summer "was normal."
Costa has revealed he didn't attempt to talk Griezmann out of joining Atleti's rivals in La Liga. In fact, Costa has said he would have told his now former team-mate it would be OK to seek a new challenge.
Atletico striker Costa spoke to YouTube channel Que Partidazo (h/t MailOnline's Kieran Jackson): "Griezmann wanted a new experience, and he'll find that in Barcelona. I didn't try to convince him to stay, but if he had asked my opinion, I would have told him that everybody should try new things.
