Novak Djokovic and Serena Williams are favourites to claim the US Open titles.

World number one Djokovic is the defending champion, and is looking to claim his third Grand Slam of the year.

Djokovic suffered a shock loss in Cincinnati, losing to Daniil Medvedev in the semi-finals, but the Serb remains in confident mood.

“I lost to a player that was playing amazing, so I’ll take that and I’ll move forward to New York and have a good practice,” he said.

“I love playing in those conditions there, center court. Gonna go to fight for a title as everyone else does, and I like my chances. I feel good, and I look forward to it.”

Whilst Djokovic is favourite, once again his biggest rivals, will be his old foes Roger Federer and Rafa Nadal.

And Federer insists that he has never felt better heading to America.

“This is probably the best I’ve felt in years coming into the US Open again, which is encouraging,” said Federer.

“I’m not putting extra pressure on myself, I know it’s going to be tough. I’m not coming in as the overwhelming favourite

“I’ve been playing well. Playing well in slams recently, which has been great. I’m happy where my game.

“I’m ready for the US Open. It’s going to be a tough tournament to win, no doubt about it. I feel like I’m part of that group who can do it.”

Nadal also arrives in good spirits, and he knows the draw has been favourable as he can’t face Federer or Djokovic until the final.

“I have to win my matches to have an advantage because I only can meet them in the finals,” Nadal said.

“I have plenty of work before that to know if I have an advantage or not. So let’s see if I am able to do my work for my side.

“That’s not an advantage or disadvantage. That’s part of the draw. That’s part of the things that happen when you are No. 1, No. 2 and No. 3. For example, in Wimbledon was the other way. They changed. Now here is the opposite.”

On the women’s side – defending champion is Naomi Osaka, although she comes into the US Open with an injury concern.
