Novak Djokovic has played down suggestions he can win Wimbledon despite looking ominously good at Queen’s.

The former world number one eased into the quarter-finals by dispatching Grigor Dimitrov 6-4 6-1 in the Fever-Tree Championships second round.

It has been a difficult two years for Djokovic after winning the last of his 12 grand slams at the French Open as he has suffered from injury and motivation issues.

But he is looking good on the grass, though is not getting carried away ahead of SW19 next month.

“Let’s not get too ahead of ourselves too early,” he said.

“I had two great matches so far, and I’ll just keep my focus here. I’m definitely not one of the favourites in Wimbledon, so I’ll just try to keep it humble.

“It’s quite open, I mean, Roger (Federer) is a clear favourite, without a doubt.

“(Rafael) Nadal maybe hasn’t played that well in Wimbledon last couple of years up to his standards, but he’s won it several times, played finals several times. He’s definitely rightly one of the candidates to win the title.

“Dimitrov, obviously if he plays on a high level, he can really beat anybody this surface. I mean, guys like that, (Sam) Querrey, (Marin) Cilic. Of course Cilic.”

Djokovic also highlighted Andy Murray as a potential threat, even though he is only one game into his comeback after an 11-month absence and has not even committed to playing at Wimbledon.

He said: “Andy and myself, you know, if we play well. Obviously we dropped in the rankings, but Andy played really well against Nick (Kyrgios) here first round.

“He has home support and a lot of things can go in a right direction for him as long as he’s healthy.

“He’s always tough to play against on grass courts, especially in Wimbledon.”

Djokovic will face Adrian Mannarino in the last eight after he won the all-French battle with Julien Benneteau 7-6 (7/4) 6-3.
