Masters champion Danny Willett has described Oakmont as "great fun" despite expectations the course is set to provide a huge test for players at the U.S. Open.

Angel Cabrera won the major the last time it was played at the Pennsylvania course, finishing at five over in 2007.

Jordan Spieth, last year's winner, expects something similar when the tournament starts on Thursday.

But Willett said the numerous options for players meant it was an enjoyable course to play.

"It's a great golf course, great fun," he said.

"There are a lot of different shots you can play.

"I think it gives you a lot of options off the tee depending upon how aggressive you want to play, but then you have to be really careful on where you place your ball around the green.

"I think the onus is on fairways and greens this week, definitely, to try to give yourself the easiest way of making par."

Willett may now be a major champion, but he played down his chances of winning back-to-back crowns.

The 28-year-old Englishman said his focus was purely on trying to get himself in contention come the final round.

"You look at the strength of the field and it would be fantastic to even be somewhere thereabouts come Sunday," Willett said.

"We're just going to have to play golf and see what happens. Hopefully, we can be somewhere there and get a little bit of a feeling for it."
