Ibrahimovic has been linked with a move to Spain this week, but Branca insists: "His reaction is normal. He's a champion and he wants success in Europe - as we all do.
"I haven't spoken to him this week - there's no need. I've seen him training and he is as committed as ever. He proved this against Fiorentina."
Branca also revealed they had tabled a new contract offer to wing-back Maxwell.
