Is Roger Federer the greatest player of all time?

It’s a timeless tennis debate and whether you think the Swiss, who is celebrating his 36th birthday on Tuesday, is or not – the numbers certainly stack up in Federer’s favour.

In 2017, the Fed Express has belied his years by winning two Grand Slam trophies – the Australian Open and Wimbledon – taking his major haul to a record 19.

That number puts him four ahead of rival Rafa Nadal (15) and seven in front of Novak Djokovic (12).

In the video below, six-time slam winner Boris Becker and former British no1 Tim Henman pay their tributes to a man they know well, while Serena Williams’ coach Patrick Mouratoglou also discusses the eight-time SW19 champion.

Federer is competing in the Rogers Cup in Montreal this week.
