On his day, Manchester United winger Nani is a world-class talent, but the Portuguese international is well aware of his infuriating inconsistency, which has been known to irritate his manager Sir Alex Ferguson.
In an exclusive interview on the Betfair Facebook page, the 25-year-old midfielder admits he is one of the more frequent victims of his manager's infamous hairdryer teamtalk.
After celebrating 25 years at the Old Trafford helm, and over 40 as a manager in the game, the 70-year-old Scot insists he has been forced to mellow as he has got older.
But Nani insists that the Red Devils boss is still capable of boiling over if the team, or any individual for that matter, is not performing to the required level Ferguson demands.
"I get it a lot, it's normal," said Nani. "He expects more from me, so sometimes he comes to me and says something.
"No-one understands it [football] like Alex Ferguson. Everyone knows him in Portugal, and talk a lot talk about him."
Ferguson is renowned for his man-management, and during his stewardship has overseen the development of a number of Manchester United's most promising young stars, including a certain Paul Scholes - who, at 37 was recently coaxed out of retirement to help the club in their title tilt this year.
"Everyone knows the way he works is fantastic and the young lads improve a lot," added Nani.
"Scholes is one of the best players I've played with in my life. The quality he gives the team is fantastic."
