Roger Federer has continued to roll back the years after cruising into yet another Wimbledon semi-final at the expense of Canadian Milos Raonic.

Federer went largely unchallenged, Raonic failing to break the Swiss maestro as Federer became the second-oldest finalist at Wimbledon in the Open era.

Federer remains on track for a record-breaking eighth title at The All England Club, and his chances of having his name etched on the famous old trophy were given a massive boost after a dramatic day at SW19.

After the dust had settled on Men's quarter-final day, Roger Federer was the only member of the top four left standing.

Andy Murray was knocked out by American Sam Querrey, while Novak Djokovic was forced to retire after an elbow injury left him unable to continue.

Federer, however, had nothing but praise for Andy Murray after the number one seed battled through the pain barrier in a desperate attempt to continue his title defence.

"Andy, I hope by playing he didn’t make things worse," said Federer.

"Yeah, it’s big for him to step out on court and give it a go, even though maybe knowing, like me last year, that chances are slim he was going to defend this title.

"I have a lot of respect for him doing that. I just hope that he comes out on the other side now not having to miss much later on.

"I just hope he can recover quickly and get ready for America really, or Canada for that matter."

Federer, who is now the absolute favourite to lift the 2017 title, admitted he did not expect to see his top four rivals falling by the wayside before the semi-final stage. 

"I’m surprised to see them going out – also Rafa [Nadal]. But the other guys are playing well. Grass court, margins are small. Still remains a great, great tournament.

"Of course, I wish them the best, that they come back strong again."

The Swiss maestro can become the oldest Wimbledon finalist if he can get the better of Tomas Berdych on Friday in what will be his 100th match on the famous grass courts of the All England Club.
