Roger Federer has called for there to be changes at Wimbledon on the back of seven players withdrawing from the tournament through injury earlier in the week.
Alexandr Dolgopolov was one of seven players to retire injured from their first-round ties, pulling out of his match with Federer on Centre Court after just 43 minutes and 10 completed games.
Another high profile retirement was that of Martin Klizan in his match against Novak Djokovic after only 40 minutes of tennis.
Federer, clearly frustrated by the withdrawal of a number of players believes, "a player should not go on court if he knows he should finish."
The seven time champion at the All England club also feels that "in the process, maybe the slams should have a look at what they could do for the players to make it just a little bit easier.”
“The question always is: should they have started the match at all? Only the player can answer really. You hope they would give up their spot for somebody else if fitness is not allowing them.”
