Sampdoria president Massimo Ferrero says he isn't surprised to see Cristiano Ronaldo leave Juventus for Manchester United.

Ronaldo's move was confirmed on deadline day for €15m plus another €8m in various bonuses.

That means Juve made a loss on the original €117m transfer fee from Real Madrid, but still benefited financially by getting his €30m per season salary off the books.

“At times it's better to give up on a few Euro rather than keep someone who doesn't want to stay with you and because of that isn't giving their best," Ferrero told Sky Italia.

“It's better for all concerned that Ronaldo left and it's better for him that he realised he was no longer the Ronaldo he wanted to be."
