Roger Federer retires from competitive tennis after dropping retirement hint earlier this year.

Tennis legend Roger Federer has announced on his social media that he is retiring from all formats of competitive tennis.

Few months a go, Tennis legend Roger Federer had dropped a huge retirement hint, admitting his time off the court the past 12 months due to a knee injury has seen him relish the daily aspects of fatherhood.

The Swiss maestro, 40, has four children and while he admitted he has missed travelling the world, the lifestyle change has been refreshing.

"I can honestly say that I am very happy at home,' Federer told Dutch newspaper Algemeen Dagblad.

'At times we (family) miss travelling, and of course I also miss the sport, but life at home is also good.'

The tennis itinerary was sometimes excessive, especially with having to organise that for the children too.'

It's nice to have a break from that now, and for them too, although they miss the travelling.'

He has undergone three surgeries on his knee and will look to play in the Laver Cup in September.

Federer has enjoyed an astonishing career, with 103 ATP single titles, 20 grand slams and an Olympic silver medal.

Fellow veteran Rafael Nadal - who has won 22 career grand slams, including the Australian Open and French Open this year - expresed his sadness at a Wimbledon press conference that Federer wasn't competing.

'My greatest rival...all the things that we have shared together on court is difficult to describe the emotions,' he said.

'I personally miss him (Federer) on the tennis tour and tennis of course misses him, tournaments, fans, everyone.

'He's a well-missed player in every single event of tennis, without a doubt.'

Today Roger Federer announced on his Instagram that he has decided to hang his Tennis racket for the final time.
