Andy Murray vs Roger Federer live stream: Watch Wimbledon 2015 semi finals tennis online (Match preview)

The No. 2 and No. 3 ranked players in the world will collide in one of two semi-finals matches in this year's Wimbledon on Friday as Roger Federer and Andy Murray try to book a place in the men's Final this weekend.

So far, Federer holds the lead 12-11 in their head-to-head matchups also winning four of the last five.

World no. 2 Federer defeated France's Gilles Simon 6-3 7-5 6-2 to advance to the semi-finals and inch closer to possibly his eighth Wimbledon title.

"I'm very happy to be in the semis again. The road is long getting here​," Federer said according to a report on Wimbledon's website.

"I still feel like I'm fresh and I've got energy left in the tank for hopefully a great match with Andy. I just hope the crowd gets into it and enjoys a good match and that we can play well. I have received a lot of crowd support over the years, and so has Andy," the 33-year-old added.

Meanwhile, Murray who ousted Canada's Vasek Pospisil in straight sets 6-4 7-5 6-4 to advance and set a date with Federer is looking for the support of the home crowd as he guns for a championship match.

"I hope I get good support on Friday. It's been the case throughout the whole event and every year that I played here," the 28-year-old British said, according to The Guardian.

He added, "Roger's extremely popular everywhere he goes, so it might not be as partisan a crowd or atmosphere as some matches that I play here. But it will still be an excellent atmosphere. I'll still get a boost from the crowd, I'm sure."

Murray will have extra motivation to top Federer in their semi-finals matchup after a string of loses in their recent meetings. The last time Murray defeated the Swiss was in the semi-finals of the Australian Open in 2013. 

The match between Federer and Murray will be played on Centre Court at 1 p.m. BST (8 a.m. ET), and can be watched online by clicking here.
