The fall-out from a disastrous Ryder Cup for the US continues this week with rifts in the team reaching the surface and claims of explosive arguments between Dustin Johnson and Brooks Koepka before and after the tournament.

There have been multiple reports that Johnson and Koepka almost came to blows during a heated argument in the aftermath of the defeat at Le Golf National.

The two players had to be separated following a flare-up inside the Europe team room, where they had joined the celebrating hosts for a beer on Sunday night.

Reports have now emerged in Golf Digest and French sports newspaper L'Equipe suggesting that the pair had an argument over Johnson's fiancee, Paulina Gretzky, on the plane to Paris before the tournament had even begun. 

Gretzky has sparked rumours of marital strife by recently deleting all pictures of Johnson from her Instagram account while sources claimed the US golf star has struck up a close relationship with socialite Yassie Safai.

The cause of the row before the tournament is claimed to be Koepka's attempts to comfort Gretzky on the flight out from Atlanta.

Koepka, however, has denied these claims, and says there was no bust-up.

"This Dustin thing I don’t get," he said, per the Daily Mail.

"There was no fight, no argument. He is one of my best friends. We talked on the phone on Monday and yesterday so tell me how we fought, I don’t know.

"People like to make a story and run with it and it is not the first time a story has come out that is not true.

"It’s actually quite funny to us as we are really good friends. There was no argument, no fight, but I’m curious who would win in a fight. It would be interesting.

"We've never fought, that’s not our relationship. We’re two even-keeled guys and I can't even remember raising my voice to him or him to me in our four years of friendship. That’s not who we are.

"We’re pretty laid back and it’s just you guys trying to make something that’s not there. We supposed fought on the plane on the way over too when we were sleeping, it’s just awful."

Koepka will be hoping to bounce back from the disappointment and controversy surrounding the Ryder Cup with a strong showing at the Alfred Dunhill Links Championship this week.
