Manchester United winger Nani knows he can get under the skin of manager Sir Alex Ferguson.

Nani, on his day a world-class talent but infuriatingly inconsistent, knows he irritates his boss more than most.

"I get it a lot, it's normal," the Portuguese winger said on the Betfair Facebook page.

"He expects more from me, so sometimes he comes to me and says something."

Not that it means Nani respects Ferguson any less.

After almost 40 years as a manager, 25 of which have been spent at United, the former Sporting Lisbon player knows the Scot is the master of man-management.

"No one understands it like Alex Ferguson," he said.

"Everyone knows him in Portugal, and talk a lot talk about him.

"Everyone knows the way he works is fantastic and the young lads improve a lot."
