Greg Norman believes Dustin Johnson can remain a dominant force for many years and warned his rivals are in for a "very hard time" as the world number one goes in search of his first Masters title this week.
Johnson won his first major at the U.S. Open last year and has gone from strength to strength since surging to the top of the world rankings in February.
The 32-year-old American will tee off at Augusta on Thursday on the back of three consecutive tournament victories and as favourite to be fitted with the green jacket for the first time.
Two-time Open champion Norman thinks Johnson will take some stopping in his homeland and feels there is plenty more to come from the man from South Carolina.
Former world number one Norman told Omnisport: "I think he made a very shrewd move not playing at the Houston Open. If he had played there I may not be so sure of his chances of winning at Augusta.
"You would have to say with how well he's playing, he is a very worthy favourite. He will be refreshed after a little break, which can only be a good thing. His odds are as they are for a good reason, he is playing incredibly well and it is no surprise at all to me.
"I would say it's not so much a sudden thing either, over the last 10 years I would say his quality has shown.
"It may have been overshadowed by some off-course issues, but he has always had amazing ability. He is in a great place at the moment, he loves where he is in life and you can see that from his demeanour.
"He is very positive and I think he can be number one for a very long time, he has everything very well balanced and it is going to be very tough for his peers, they are in for a very hard time with him as he is at the moment."
