Jon Rahm says he is targeting a lengthy spell as new World No.1.
The Spanish golfer replaced Rory McIlroy at the top of the rankings following his victory in the Memorial Tournament, the 25-year-old becoming just the second Spanish player after Seve Ballesteros to achieve the feat.
McIlroy will regain top spot with a win in this week's WGC FedEx St Jude Invitational regardless of where his rivals finish, but Rahm is determined that will not transpire.
"It's an honour (to be No.1)," Rahm told a pre-tournament press conference at TPC Southwind in Memphis.
"It's something I set out to accomplish a long time ago.
"It's humbling to be here knowing how hard I've worked to get to this point and to be the first Spaniard since Seve, knowing how some of the greatest golfers in history from Spain and Europe haven't been able to get there.
"Even my close friend Phil (Mickelson), a five-time major champion wasn't able to get there.
"It is true some of those players had Tiger (Woods) at the time and no one was going to take that from him, but it doesn't take away from what I've done myself.
“Getting here (World No.1) is great and I've played great golf the last few years but I can only help to think that I need to keep playing that good or better to hopefully stay here for a long time.” – Jon Rahm
"At the same time, getting here is great and I've played great golf the last few years but I can only help to think that I need to keep playing that good or better to hopefully stay here for a long time.
"It's what I've set out to be and that's a goal I think for a lot of us, trying to be consistently good and play good golf throughout our careers."
While Woods spent a record 281 consecutive weeks as World No.1 between June 2005 and October 2010 and 683 in total, the top spot has changed hands far more frequently in recent years.
Since March 2016, Jordan Spieth, Australia's Jason Day, Dustin Johnson, Justin Thomas, Justin Rose, Brooks Koepka and McIlroy have all been top-ranked and it is even mathematically possible – albeit a long shot – for McIlroy and Rahm to share top spot on Sunday evening.
"Nowadays it's really tough to determine one player (who is the best)," Rahm added.
"Brooks is having a hard year right now but he has won four majors in the last few years. Rory played amazing last year.
"It's hard to dictate one player alone, but it would be foolish for me to say that I'm not here thinking I'm the best player.
"And I think all the great players who have got to this point believe they are the best and I think you have to try to prove that every week."
