Marin Cilic was full of tears on Sunday as he was beaten by Roger Federer in the Wimbledon men’s final.

Devastated Cilic admitted his Wimbledon final tears were triggered by the realisation his bid to shock Federer was destined to end in a painful defeat.

Cilic wept inconsolably on Centre Court midway through the second set after calling for medical attention on a nasty blister on his left foot.

The former US Open champion gamely played through the agony, but couldn't stop Federer cruising to a 6-3, 6-1, 6-4 victory.

"I got a bad blister in the semi-final against Sam Querrey. Fluid just came down under my callous in the foot," Cilic said.

"The physios here helped me over the last 30 hours. They were with me constantly and did as much as they could.

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

"Obviously it was very tough emotionally because I know how much I went through in the last few months in preparation for Wimbledon."

Cilic explained that his tears at 3-0 down in the second set were more a result of his disappointment at not being able to perform at his best rather than a legacy of the pain.

"It was just a feeling I knew I cannot give my best on the court, that I cannot give my best game, especially at this stage of my career, at such a big match," he said.

"It was very, very difficult to deal with it. It didn't hurt so much that it was putting me in tears. It was just that feeling that I wasn't able to give the best".
