World No 1 Jannik Sinner still sees room for improvement after advancing at Wimbledon

After being pushed to five sets by Serbia's Miomir Kecmanovic in the opening round, Sinner has responded with straight-set victories over Nuno Borges and Jenson Brooksby to ease into the second week of the tournament.

The Italian will next face Japan's Shintaro Mochizuki for a place in the quarter-finals.

Reflecting on his performances after his first three matches, Sinner said he believes there is still room for improvement as he looks to reach his top level during the tournament.

"Yeah, I'm trying to find my way in. Felt better today, which was my main goal. Especially how I ended the match," said the World No 1.

"The last game, I was going for it a little bit better. So hopefully this gives me confidence then to start the next match in a positive way.

"But in any case, trying to move better. Return today was a little bit better. Yeah, so all things considered, was a small step forward. I still have some gap to gain. Hopefully I can do that from the next match."

Asked where he thinks he should be at this point in the Grand Slam, having won the tournament last year, he responded with a typically diplomatic answer.

"I mean, it's tough to say," said Sinner. "I feel like every year is different. For sure you don't win a tournament in the first week, but you can only lose it.

"It's always a good sign that I'm still here. Of course, we try to make always small steps forward, then we see how it goes. But all things considered, haven't played any tournament before on grass.

"First couple of matches always tough. Now trying to find a way with a good rhythm slowly in the tournament. Then we see also next round how it goes, how I start off, and we talk from there."

Sinner's forehand has been his weakness so far, which is a surprise at it is usually one of his biggest weapons.

The star is also set to deal with another issue in the second week of the Grand Slam, as the UK is set to be struck by yet another heatwave.

Temperatures are set to hit 32 degrees Celcius at Wimbledon next week, which could be a worry for the World No 1.

Sinner has struggled in the heat previously, most notably at Roland Garros against Juan Manuel Cerundolo and at the Australian Open against Eliot Spizzirri earlier this year.
