Rory McIlroy believes he is playing the best golf of his life and has described his summer as beyond his "wildest dreams" after securing the US PGA Championship.
The triumph represented McIlroy's second major in as many months and his fourth in his career after winning the Open Championship in July.
McIlroy managed to see off challenges from Phil Mickelson, Henrik Stenson and Rickie Fowler as all three aimed the win the final major of the season at Valhalla. His gutsy win pleased the Northern Irishman and it suggested he is more than capable of digging deep and grinding out a victory.
"I gutted it out," McIlroy, who wrapped up victory in the gathering gloom by one shot, explained. "It was different from my previous major wins. "To win my second major this year and a fourth by the age of 25, it's just incredible.
"I'm going to celebrate and share it with the people who are close to me. I'll be back home in Northern Ireland at the end of the week."
McIlroy says that he was just hoping to push on after winning the Open Championship but couldn't imagine having such an impressive summer.
"Winning the Open was huge for me and I said I wanted to back it up," added the Northern Irishman. "I didn't think in my wildest dreams I would have a summer like this. I just played the best golf in my life."
McIlroy's remarkable summer also included victory at the WGC Bridgestone Invitational in Kentucky as he narrowly beat Sergio Garcia.
Off the course, McIlroy made headlines after his high-profile split with tennis star and fiancee Caroline Wozniacki but won the BMW Championship at Wentworth during the same week.
His four wins in 2014 and seen his reclaim the world number one spot and shows a stark contrast to this time last year when he was winless.
The 25-year old is now looking forward to having a week off after his recent successes and the Manchester United fan is planning to catch up with other sports during his short break.
"I've got a week off now and I'm going to enjoy it," McIlroy told BBC Sport.
"I don't know if I can parade both the Claret Jug and the Wanamaker Trophy at Old Trafford on Saturday. I'll try!"
After his break, McIlroy will be setting his sights on Jack Nicklaus' record of 18 major victories. He has already emulated Nicklaus' feat of winning four majors by the age of 25 but has a long way to go if he wants to beat him.
