Masters champion Trevor Immelman reckons teen sensation McIlroy has the X-factor required to win at Augusta.

Set to calsh with the Holywood star at this week's Honda Classic, Immelman said: "It's definitely not impossible. Fuzzy Zoeller did it in 1979 and although Tiger had played three times as an amateur it was his first as a pro when he won in 1997.

"Obviously there's going to be a lot of pressure on him and he's going to have feelings that he has not had before mentally and emotionally.

"He has all the physical talents, but a there are a whole host of guys who do and there's a little bit of an X-factor in doing something great in sport.

"Players find that out when the moment arises and time will tell whether he has that little X-factor."
