Luke Donald reflected on his new status as world number one and said: "Sounds pretty good, doesn't it!"
Donald snatched top spot from Lee Westwood after beating his fellow Englishman in a play-off at the BMW PGA Championship at Wentworth - the European Tour's flagship event.
"I'm not sure if there will ever be a case where number one and number in the world are playing off for the tournament, but also a chance for the number one ranking in the world," said Donald.
"But a unique history I think has been made, and I'm glad to be a part of it.
"As I said before, it's something that will be a great story when I'm an old man telling my grandkids that I was once the best player in the world at golf. It's a little surreal. It's hard to believe in a certain way. You keep thinking that you have the ability and the talent, but you never quite really know.
"Whether it will change me, I don't think so. The goal for me is to always continue to focus on the processes of getting better, and just because I have reached the pinnacle of the world rankings doesn't mean my work is done.
"I have a lot more to accomplish, hopefully many more victories in me, and hopefully I can at least be somewhat of a worthy number one for a few weeks."
Donald's victory at Wentworth was the culmination of some fantastically consistent golf and his claiming of the world number one ranking was a case of third time lucky.
He was second at the Volvo Match Play in Spain last week and also at the Heritage tournament after a play-off in South Carolina last month. On both occasions a win would have made him number one
His Wentworth win was his ninth successive top-10 finish, a run that began with his victory at the WGC-Accenture Match Play in Arizona in February.
In that run he has earned over £3million - and that works out at £77,140 for every round, or over £4,200 for every hole.
