A place in the final of Wimbledon was at stake for Thomas Berdych as he prepared to take on Roger Federer at the All England Lawn Tennis Club.

But a second Slam final wasn’t the only thing on the Czech’s mind ahead of the match.

Berdych was obviously sparing a thought for Novak Djokovic, who he beat in the last eight to reach the semis. The Serb was forced to retire through injury as Berdych led 7-6 2-0, and the 11th seed seemingly felt bad enough on Djokovic that he decided to pay tribute to him during his match with Federer.

As he walked out on centre court, he was photographed wearing a special pair of shoes. On the tongue of his Adidas trainers was an image of Djokovic’s face etched into the material.

Djokovic, who would have replaced Murray as number one in the world had he been able to continue in the tournament, admitted he may now be forced to take an extended break from tennis.

“Now I am paying interest for all these years as a professional, my body is giving me signals,” said Djokovic.

“I may take a longer breaks than the ones I have previously taken. The more I play, the worse it gets. I guess the break is something that I will have to consider right now.”
