Djokovic backs Murray to return despite Wimbledon farewell

Novak Djokovic on Thursday backed Andy Murray to keep playing despite the insistence of his career-long rival that he is bidding farewell to tennis this year.

Djokovic and Murray have been rivals since they were 12 years old and have clashed 36 times as professionals. That includes seven Grand Slam finals.

"I do wish him all the best in his farewell," said Djokovic.

"But I wouldn't be surprised if he decides to come back again. He's an incredible competitor -- resilience that you can definitely study and teach young athletes."

Murray pulled out of Wimbledon singles after failing to recover from a back operation but is playing men's doubles with brother Jamie on Thursday and mixed with Emma Raducanu later in the tournament.

The former world number one and three-time major winner said he will retire after the Paris Olympics.

"If this is his last match, obviously it's sad that he's not able to finish in his own terms in singles," said Djokovic.

"Playing alongside his brother is probably even more emotional for everyone -- for them, for the family."

Earlier Thursday, Djokovic was made to fight by British outsider Jacob Fearnley before reaching the Wimbledon third round for the 18th time.

Seven-time champion Djokovic triumphed 6-3, 6-4, 5-7, 7-5 but had to save two break points midway through the fourth set before seeing off the challenge of the world number 277.

"I had never seen him play so there is always the element of surprise," admitted Djokovic.
