The Northern Irish golfer completed the career Grand Slam with an emotional success at Augusta at the weekend and his putting instructor Brad Faxon believes that the victories will flow now he has ended an 11-year wait to win one of the game's four biggest titles again.
Faxon said: "He has played professional golf for more than half his life now and there is nothing that can stop this guy.
"Rory can double his number of majors – he can go on to win 10. Something happened from the defeats to build the resilience he has. It builds inside what you need to overcome. He is an example to everyone."
McIlroy has finally landed his first Green Jacket and Faxon praised the world number two for coping with the pressure of trying to join golf's most elite club during a dramatic week at Augusta as he secured a fifth major title.
The coach said: "Rory has carried a burden since 2014 to have this goal accomplished and every year, since the first major of the year, it gets harder every year.
"Rory is one of the most intelligent, kind people I have ever met in my life and he knows everything about the history of the game and what this means for the game."
McIlroy's friend Paul McGinley has tipped the golfer for more major wins this year after finally getting the Masters monkey off his back.
The former Ryder Cup captain said: "Now that he’s climbed Everest, does he lose a little bit? When you reach something you’ve desired so much, you kind of soften... but I don’t think so. I think he’s going to keep going. I’ve said if he’ll win one major, he’ll win three or four. I don’t think he’s done winning majors this year. He’s got some great chances to add to it – maybe a double, a triple, or maybe even a grand slam this year? How about that?"
