Centre Court is packed. Henman Hill is packed. Courts One, Two and Three are all packed.

The big screens on those courts are all showing this match with fans desperate just to be close to the action and soaking in the atmosphere.

Since rising to world number one last year, Jannik Sinner has reached nine championship matches and won six of them. All three losses have come at the hands of one man - Carlos Alcaraz.

The men's singles final at Wimbledon attracts the great and the good from the worlds of entertainment and sport.

Keira Knightley, Nicole Kidman, Dame Anna Wintour, former Wimbledon champion Andre Agassi and Olympic gold medallist Sir Chris Hoy are among those in attendance.

For nearly two decades, the rivalry between the Big Three - Roger Federer, Novak Djokovic and Rafael Nadal - dominated tennis.

The Serb is the only remaining active player of the three, while Jannik Sinner and Carlos Alcaraz will compete in a second consecutive Grand Slam final.

So is their rivalry tennis' new match-up?

"You cannot compare what the 'Big Three' did for 15-plus years. [Our rivalry] is not that big yet," said Sinner.

"This is the second consecutive Grand Slam that we are in the final and playing each other - I believe it's good for the sport.

"The more rivalries we have from now on, the better it is, because people want to see young player going against each other."

Here come the lads!

A standing ovation greets Jannik Sinner and Carlos Alcaraz as they stride out on to Centre Court.

It is the first time in the Open era where the top two men's players have contested the final at the opening three Grand Slam tournaments.

The excitement is palpable. This is what tennis is about. This is what sport is about.

Drink it in.

Big cheers as Jannik Sinner leads Carlos Alcaraz out of those famous doors and on to Centre Court.

All eyes and cameras trained on the Royal Box as William and Catherine, the Prince and Princess of Wales and two of their children, George and Charlotte, make their way to their seats on the front row.

Almost time.

Incredible scenes on court 14 today as fans clambered for a look at the two-time defending champ Carlos Alcaraz.

He appears to have rock star status here at SW19.

I'm not going to lie to you all I've just been for a last-minute loo break (well aware we could be in this for the long haul) and I've just seen someone drop an ENTIRE POT of strawberries and cream.

Absolute heartbreaker.

There may be little to separate these two but Jannik Sinner and Carlos Alcaraz are miles ahead of the chasing pack at this time.

The pair have won the last six Grand Slams between them - and seven of the past eight.

There have been so many great rivalries in tennis. They [Sinner and Alcaraz] remind me of Nadal and Federer, myself and Bjorn Borg.

That's what makes it great. The way they behave out there is completely different but both equally effective.

Sinner was only one point away from winning the French Open. You have to move on from losses and think that it's just another game. This will be a bigger match for Sinner - his first Wimbledon win.

Alcaraz is going to try and outplay Sinner, just like Dimitrov did for the first two sets. Carlos is one of the best players I have ever seen. He has one of the best attitudes and is one is the most complete players. That is so impressive. When Alcaraz brings his 'A' game, he is unbeatable.

So much to talk about with this one.

BBC pundit Pat Cash takes a look at where the final will be won and lost.

This will be the second time that these two generational talents face one another in a Grand Slam final.

But, you suspect, it will not be the last.

Despite the brutal fashion in which he lost the French Open in five sets, there was genuine warmth between Sinner and Alcaraz after the match at Roland Garros.

"It's a huge honour for me to share the court again with Carlos," Sinner said.

"Hopefully it will be a good match like the last one - I don't know if it will be better because I don't know if that's possible but we will try - hopefully it will be an enjoyable match."

These matches are so multi-layered. They take many twists and turns, even during the course of a match.

Even their rivalry, the same way we saw with Djokovic and Nadal or Federer and Nadal, matches evolve over time.

It’s interesting to see if there are any changes that have taken place [since the French Open final].

Carlos Alcaraz has won eight of his 12 matches against Jannik Sinner - including the last five.

Since the start of his title-winning run at the China Open in September 2023, Sinner has lost just 11 of the 127 matches he has contested - meaning almost half of his losses in that time have been to Alcaraz.

However, the last time these two met at Wimbledon in 2022, it was Sinner who came out on top.

The last time Carlos Alcaraz and Jannik Sinner met in a Grand Slam final it turned into an epic encounter lasting almost five and a half hours.

Now, 35 days on from that French Open thriller, they will meet again in Sunday's men's final at Wimbledon.

After ending Novak Djokovic's hopes of achieving a 25th Grand Slam title, world number one Sinner was asked what fans could expect when he faces Alcaraz once again.

"We saw the last final - you never know [what will happen]," he said.

"Hopefully it's going to be a good match like the last one, I don't know if it can be better because I don't think it's possible.

"But we will do our best."

There are a number of factors that turn an exciting rivalry into an epic, enduring duel that transcends the sport.

The core talent. The blend of personalities. The gripping encounters on the biggest stages.

The tussle between Italy's Jannik Sinner and Spain's Carlos Alcaraz - ranked one and two in the men's game - has all those components.

It also has arguably the most important ingredient: each player being pushed to a greater height by the other.

On Sunday, the pair will meet again in the Wimbledon final - where Sinner aims to win his first title and Alcaraz bids for a rare third in a row.

A renewal of their acquaintance at the All England Club comes just 35 days after Alcaraz beat Sinner in an all-time classic French Open final.

Asked about their rivalry, Alcaraz said: "I'm not going to say I'm feeling like when Rafa [Nadal] and Roger [Federer] are playing.

"But I'm feeling like it is a different energy when we are facing each other than other players."

We're hearing that Jannik Sinner and Carlos Alcaraz will walk out onto Centre Court at the slightly later time of 16:10 BST.

Time to stock up on snacks, drinks and all that jazz. If the last final between these two is anything to go by you're going to need them.

Good afternoon friends...

It's here. The big one.

Round two of this growing rivalry at a second consecutive Grand Slam.

Jannik Sinner v Carlos Alcaraz. World number one v world number two.
