Men’s tennis world number one Novak Djokovic has said that wheelchair tennis players are a source of inspiration for him.

The three times US Open champion also hailed the tournament organizers for including and providing opportunities for people with disabilities.

The Serbian international will take on Spain’s 20th seed Pablo Carreno Busta in the last 16 at Flushing Meadows as he aims to edge closer to an 18th Grand Slam title.

Djokovic posted his admiration for wheelchair tennis players when discussing with five time Grand Slam wheelchair champion Gustavo Fernandez.

“Gustavo and I talked tennis today, Wheelchair tennis players are truly an inspiration for me, he said on his verified Facebook page.

“It’s amazing how they manage to execute the shots while constantly having one hand on the wheel.

“Gustavo was kind enough to answer all the questions and give me insights to his Herculean efforts on the court.

I have tried several times to play wheelchair tennis and it’s super hard. Big admiration and respect to Gustavo and all the wheelchair tennis players.

“Well done to @usopen for providing opportunity for these guys to compete in these kind of circumstances.”
