After last night's 0-0 Champions League draw, Dybala was asked about his Argentina teammate's future.
"Messi's future will be decided by him and his environment. I'm not the one to say anything, just to say that it would be strange to see him wearing another shirt when he's always worn it," he said.
"I was surprised when I saw that Messi was not on the pitch."
Barca coach Ernesto Valverde chose not to start the game with Messi.
