For Marin Cilic, Sunday's Wimbledon final could not have gone much worse.

Having progressed through the tournament showing nerves of steel, the big Croatian crumbled when it mattered most - against Roger Federer on centre court.

He certainly isn't the first to get overwhelmed by the occasion of taking on one of the sport's all-time greats with the eyes of the world watching on and he won't be the last either.

Federer claimed a record eighth Wimbledon title and his 19th Grand Slam with a relatively straightforward 6-3 6-1 6-4 victory over the seventh seed.

The Swiss who, like Rafael Nadal at the French Open, went through the entire tournament without dropping a set and has become at 35, has become the oldest winner at SW19 in the Open era.

In what was an otherwise rather disappointing final from a neutral's perspective, arguably the biggest talking point came during the second set when, at 3-0 down, Cilic became visibly upset.

At the change of ends, the Croatian was spoken to by doctors and physios although they didn't actually provide him with any treatment so it was hard to work out exactly what was wrong.

Shortly after, Cilic did receive treatment on a problem with his foot and he has now explained why was so emotional.

"It was definitely one of the unfortunate days for me to happen," he said, as per The Metro.

"I got a really bad blister. Even I felt it in the match with Querrey in the semis. Fluid just came down under my callous in the foot.

"Every time I had to do a reaction fast, fast change of movement, I was unable to do that.

"Obviously was very tough emotionally because I know how much I went through last few months in preparation with everything. It was also tough because of my own team. They did so much for me. I just felt it was really bad luck.

"But in any point, obviously if the score would go really badly, I wouldn’t push it so much. But I really wanted to give my best, you know, to try as much as I could.

"It was just emotionally that I knew on such a big day that I’m unable to play my best tennis, in physical, and in every single way.

"That was just a little bit combination of all emotions because I know how much it took for me to get here."

It was the first time Cilic had reached the last two at SW19 but of course, not his first Grand Slam final after he won the US Open in 2014.

And at 28, he is still young enough to have plenty more cracks at going one step further at Wimbledon. He only needs to look at 35-year-old Federer!
