Rory McIlroy has targeted becoming the sixth different player to win all four golf majors at next year's Masters after claiming the US PGA Championship at Valhalla.

McIlroy prevailed by one-shot in Kentucky to win his second major in a row after claiming July's Open Championship at Hoylake and he already has designs on joining the sport's elite.

Only American quartet Jack Nicklaus, Tiger Woods, Ben Hogan and Gene Sarzen and South African Gary Player have won all four major titles in the Masters era and McIlroy is aiming to become the latest addition to that illustrious list.

"It [The Masters] is the only one I haven't won," he said. "I desperately want to win the Green Jacket.

"I am not going to try too hard and I know that if I play my game and the golf I am capable of there is no reason I shouldn't go to Augusta thinking I can win and complete the career Grand Slam."

The world No.1's victory at the US PGA Championship was his third successive victory having won at the Bridgestone Invitational earlier this month following his Open success, and with the Ryder Cup on the horizon the 25 year old is preparing for some time off after a life-changing summer.

"I am going to enjoy this week. I have a week off. It has been a great summer. I am not sure if I am ever going to have another summer like this," McIlroy added.

"I will be back home in Northern Ireland at the end of the week. I don't know if I can parade the Claret Jug and the Wanamaker Trophy at the same time at Old Trafford on Saturday but I will try.

"I will go to Old Trafford for the first game of the season on Saturday and bring the Claret Jug with me. That will be a great thrill and then come back over to the States and get ready for the FedEx Cup.

"I want to let this all sink in. It has been an incredible run of golf and one I will always remember. I may never have a summer as good as it has been in 2014."
