The Royal Box is empty at the moment. Or maybe Sir Cliff is sat there and he is just camouflaged by the green seats...

The hair! The chubby cheeks! The stubble! Roger Federer's look may have changed since his first Wimbledon title, but his elegance around the court and winning mentality has not.

It is 14 years since the Swiss won his first major title when he beat Australia's Mark Philippoussis on Centre Court, and five since he beat Andy Murray to win his last Wimbledon title.

"I don't feel like [2012] is that long ago, to be honest," he says.

"2003 feels like ages ago, because of the ponytail, the beard, whatever, you name it. This one is different. I kind of look the same as back in 2012, or at least I hope so."

...can Roger Federer become the second?

It's all about who can handle the pressure of a Wimbledon final because there's so much at stake. Physicality will be an aspect of it but both men will run until they have nothing left.

Looking down onto Centre Court from the BBC Sport commentary box (sorry, I'm not showing off - honest), there are plenty of Swiss red and white tees and caps with 'RF' emblazoned on them.

The Fed Heads are here. This is a home match for the 18-time champ.

Later it will feel like we're in Basel....

They say don't meet your idols. Marin Cilic did, when he was a teenager. And then this hero became his coach.

Goran Ivanisevic took his fellow Croatian under his wing, coaching him from 2013 and helping him win the US Open the following year.

"I met him when he was 14 years old and he didn't hit a ball in the court," said the 2001 Wimbledon champion.

"I predicted then he would be a top 10 player - and I was right.

"I said he would win a Grand Slam and people looked at me like I wasn't normal.

"He was special."

Marin Cilic's path has been a little tougher in terms of shift times.

The Croatian has been on court for 14 hours and 28 minutes in his six matches at Wimbledon so far, compared to just nine hours and 56 minutes by Federer.

Choo choo! The Fed Express is coming through...

The seven-time champion has not dropped a set on his way to the final and has only had one match that has lasted more than two hours - his semi-final against Tomas Berdych.

A fortnight ago there were 128 men who dreamed of being one of the last two standing. Some fancied their chances, some were being fanciful.

We've seen thrills, we've seen spills. We've seen shock wins, we've seen shock withdrawals through injury. We've seen sunburnt skin, we've seen sunburnt baselines.

So much has happened it is easy to forget how Roger Federer and Marin Cilic arrived here. Luckily we've got a reminder...

The men's tournament was always about the big four but the legend is in the final and I think the greatest will prevail.

Eeek. We're little under an hour away from Roger Federer and Marin Cilic walking out onto this small patch of SW19 grass.

Centre Court is filling up slowly, a hum of excitement growing louder by the second.

While one woman sits in the stand unwrapping her tin foil-covered sandwiches, others pose for the perfect photograph at court-side.

I've also spotted one young lad already sat in his seat, in the line with the baseline opposite the Royal Box... with his lower left leg covered in plaster.

Even broken limbs don't keep ticket holders away from Centre on finals day.

When you walk out on Centre Court if you show one ounce of fear the other guy will take advantage, especially someone like Roger Federer who has been in so many finals here.

Cilic didn't always believe he could win these but now under coach Jonas Bjorkman he has that belief. You cannot hide your fear on Centre Court so you have to have belief in your game.

Of course, Marin Cilic might have something to say about that. The Croatian seventh seed has not turned up to gawp at a procession by King Rog.

He's come here to win.

Cilic knows what it takes to win a Slam, having triumphed at the 2014 US Open, but this is his first Wimbledon final.

Got to be a few butterflies fluttering around in even the strongest of stomachs.

....and today we could see a king crowned on Centre Court....

Arise King Roger the Eighth!

Prince Albert, later to become King George VI, AKA the Queen's dad, even played in the men's doubles in 1926. He lost in straight sets.

Queen Elizabeth did not inherit her dad's love for the game, however, and is rarely seen at Wimbledon.

But she did turn up in 1977. Something big happened that year. Although Our Liz looked a little bemused by the occasion...

Royalty and Wimbledon have a long history.

Way back in 1907, Prince George and Princess Mary were the first members of the British monarchy to watch on from the grandeur of the Royal Box.

Since then we have seen King George V and Queen Mary shake hands with legendary French player Suzanne Lenglen...
