Carlos Alcaraz even got it done in good time to watch the football.

He had retained his Wimbledon crown, he had completed the Roland-Garros-Wimbledon double, he had clattered Novak Djokovic in straight sets. And there were still hours to go before the kick off. It had been a perfect day.

The Spain team had been supporting Alcaraz as they made their way to the UEFA European Championship final in Germany. Now he was determined to return the favour.

Now it was his duty to return the favour (even if it meant sneakily watching the game on his phone during the Champions’ Dinner).

“I will watch it for sure on the phone the first half,” the smiling champion said. “The second half I will watch on the TV over there. I can't miss it.

“It's going to be a really big moment for the Spanish people. As they [the Spain team] were watching my final, I have to watch their final and support them.”

For the past 20 years we have been comparing the records of the three GOATs (Greatest Of All Time): Roger Federer, Rafael Nadal and Novak Djokovic.

But Alcaraz has already achieved something that none of them could – he now has four Grand Slam trophies in his collection, all won before the age of 22. He is only just getting started.

“At the end of my career, I want to sit at the same table as the big guys,” he said. “That's my main goal. That's my dream right now. It doesn't matter if I already won four Grand Slams at the age of 21.

“I don't know what is my limit. I don't want to think about it. I just want to keep enjoying my moment, just to keep dreaming. So let's see if at the end of my career it's going to be 25, 30, 15, four [Grand Slams]. I don't know.”

So he is learning from the GOATs about being a GOAT. And he is learning fast. Even in the past 12 months, he has learned about winning on Centre Court. Last year it was all new; this time he felt that he knew exactly what he was doing. He had done this before.

Preparing for the final felt different to last year (even if winning felt just as good if not better).

“I felt like I wasn't new anymore,” Alcaraz said. “I've been in this situation before. What I did wrong last year, tried not to repeat it, be better on that side.

“Yesterday I was calmer than last year. For example, I tried not to think about the match or just for a few moments watching some videos. But apart from that, I try not to think about it.

“Today I think I did a really good warm-up. Just one hour and a half, one hour before the match I started to feel the nerves. Before that, I was really calm. That help me a lot coming to the match.

“I managed pretty well the match. I remember in that last year's final, it was pretty different things. Really much better for me.”

From a scratchy start in the opening round (his serve was misfiring) Alcaraz had worked and improved with every passing day. By the time he faced Djokovic, his serve had been honed to perfection – it was battering Djokovic into submission – while his forehand was simply ferocious. But he wants more; much more.

“I have to keep improving everything, I guess,” he said, simply. “My forehand, at this level I think it can be better. Every year should be better.

“I think my game in general I think can improve it and deal with the situations. I can't stop like [after] this one. I have to keep growing up and keep improving.”

Djokovic, and everyone else in the locker room will be delighted to hear that.

Alcaraz is setting up a rivalry with the 22-year-old Jannik Sinner, the current world No.1 and those two are putting clear water between themselves and the rest of the field. And now Alcaraz is planning on being even better.

Still, all of that could wait until tomorrow. There was a Wimbledon title to celebrate and the football to watch. Vamos Espana!
