McEnroe believes that ultimately nothing will change and that the best players will still remain on top but he also believes that the key is definitely arriving early.

“The best players are going to be the best players,” McEnroe told ATPTour.com. “The cream will rise to the top.”

“Get there as early as you can and obviously the people who play 'Cincinnati', you’ve got to think that’s smart. I would get out there and play as many sets as you can,” he added. “Play as many real practice sets and matches with other players as you can to try to get sharp. I’m sure all these guys have been training and hitting a bunch of balls, but it’s always different when you go out for match play."

But similarly, he doesn't see the winner being a surprise but that he doesn't see Djokovic automatically winning in the end.

“People say, ‘Oh, maybe someone’s going to come through and win the US Open. Maybe someone who is like Thiem or Tsitsipas who’s already there. I don’t see someone coming out of nowhere. That just doesn’t happen. I don’t see that happening,” he continued. “That’s not saying it’s a lock that Djokovic is going to win. You can certainly make the argument that he might be more susceptible. But I don’t see someone coming out of nowhere and winning the Open.”
