LIV Golf are competing at the 125th U.S. Open at Oakmont, with many expected to perform well. These are the ones we need to watch.

Of those playing in the U.S. Open who compete for LIV Golf, four of them are past champions, including Bryson DeChambeau, who won his second U.S. Open title last summer at Pinehurst No. 2. Dustin Johnson captured the U.S. Open title the last time the championship was contested at Oakmont in 2016.

Jon Rahm knows Oakmont Country Club will provide a challenge unlike any other at this week's U.S. Open but the Spaniard said on Tuesday the aura of one of the most feared layouts in the world will not impact his game.
