Giovinco's agent has admitted contact with Barca in recent weeks.
The former Juventus striker told Calciomercato.it: “I owe so much to Toronto because they allowed me to win this award and I will do everything to win it again both personally and with the team.
“Payback? I'm glad I made this choice and that's the most important thing.
"I didn't think about the criticism, I have always tried to enjoy myself. Sometimes I succeeded, but other times not, but I'm looking ahead on my path.
"Messi is the best in the world, I knew nothing of an offer. The interest makes me very, very happy.
“Next year? I don't know, now I've finished this one, we'll see about the next."
