New US Open champion Jordan Spieth has revealed that he is plotting to become world number one and take over from Rory McIlroy.

Spieth won the tournament by one shot at Chambers Bay to add the US Open to the Masters title he won in April.

He is quoted as saying in The Telegraph: "To have two players holding the four Majors is awesome – the game is in young hands. I don't think much of a rivalry. I've said that from the beginning. Rory has four Majors and dozens of wins and I'm just starting out.

"But I'm certainly quite a bit younger than he is. I'm just happy to have these two titles and to be chasing that number one spot which he holds. I'm certainly focused on that."

Spieth will continue his assault on the season's four Majors at the Open Championship next month.
