Jannik Sinner knows the big serve of Alexander Zverev will be a major threat to his hopes of capturing back-to-back Wimbledon titles, as they prepare to play Sunday's final in searing heat.

After storming past Novak Djokovic with a clinical semi-final display, Sinner is the first world number one to reach back-to-back Wimbledon finals since the Serbian did so in 2019 and 2021, either side of the tournament taking a year off due to Covid-19 in 2020.

The last player to win consecutive titles at SW19 while sitting top of the ATP Rankings was Roger Federer, who won four in a row as world number one from 2004 to 2007.

And Sinner holds a 10-4 advantage over Zverev in the pair's head-to-head record, which includes nine victories in their last nine meetings.

That is the most consecutive matches any player on the ATP Tour has ever won against the German, but Sinner is not expecting an easy ride in Sunday's showpiece match.

With temperatures of around 30 degrees Celsius anticipated, Sinner believes the contest may be decided by both players' ability to serve big and keep rallies short. 

"There will be fewer exchanges, less rhythm," Sinner told reporters when asked how he expected the final to play out. 

"This we know, because of the surface being that fast. Being also quite warm, it's going to be good for a big server, and he is definitely a big server!

"Whatever happened in the past between me and him, it happened. In between, he won a grand slam in Paris, which gave him a lot of confidence. We can see the level he's producing here. We all hope for a good match.

"When you start to win a lot of matches and don't lose a lot, it shows that he is playing incredible tennis. 

"I saw a little bit [of Zverev] in the two weeks, but not so much. I saw the semis because he was playing before me, so I was watching. He is very, very aggressive at the moment.

"His confidence is good. He's very relaxed on court, so that is good. Let's see. I'm happy to face him. I'll try to do the best I can, and then we'll see how it goes."

While Sinner is eyeing his fifth grand slam title, Zverev is targeting a second major triumph in quick succession, after downing Flavio Cobolli in a five-set final at Roland-Garros last month.

Zverev had been threatening to win a slam for several years, since going down to Dominic Thiem in his first major final at the 2020 U.S. Open.

Thiem never managed to win another grand slam crown, but Zverev believes the emotional nature of that final made it uniquely difficult for his rival to return to those heights. 

"I think Dominic Thiem in particular put his whole life and soul into winning that slam. He came back from two sets down against me in the U.S. Open," Zverev said.

"I think it was such a relief for him that it was maybe a bit too much of a relief, mentally. For me, I stay focused. I stay hungry. I want more.

"I want to continue playing at the best level and continue winning. I hope I'm able to do that, and on Sunday, I have another big chance."
