The four-time Major winner has spent 47 weeks atop the Official World Golf Ranking but lost the No.1 spot to McIlroy in February
Koepka Targets World No.1 Spot - "I've Got Eyes On Rory"
Koepka returns to action this week at the Charles Schwab Challenge, where he finished 2nd in 2018, and his game is "a million times better" now than before the Coronavirus pandemic took hold of the PGA Tour season.
"I'm just trying to play the best golf I can play," he said.
"I've got eyes on Rory. That's the goal is to get back to No. 1 in the world. That's the whole point of playing is to be the best.
"If I do what I'm supposed to do, if I take care of my business, then I don't see any reason why I couldn't get back to that.
"I dug myself a hole, obviously, getting injured and then when I started back up the first three months of back playing or two months back playing. I dug myself a little bit of a hole.
"But you play good, you win, everything will take care of itself."
Koepka has spent 47 weeks as the world's number-one player, first reaching the top after his CJ Cup win in October 2018.
