The Portuguese winger said: “Alex Ferguson shakes me up and screams at me now and again.
“He is like my mother or my father. He sets my limits and my aims.
“People say he is less explosive than before, but he can still get angry.
“He has often shouted at me during half-time, but always to make me progress. He is fair.
“Everybody said he was past it, that the team could not win the Premiership. But as he predicted, the team gained in maturity, consistency and balance. All the players scored goals this year.
“Ferguson knew that was going to happen. He has always been in control.”
