Roger Federer (PC: Twitter)
Tennis great Roger Federer announced his retirement on social earlier this evening.
The 20 time Grand Slam champion confirmed the development on his social media accounts and the tributes have been pouring in from the sporting fraternity.
The 41-year-old is widely regarded as the greatest Tennis player of all time and he will be seen in action in the Laver Cup in London next week. It will be the final professional participation of his illustrious career.
Federer has had his fair share of injury problems over the years and he has been struggling with persistent knee issues over the last three years.
The Swiss international has now revealed that he is fully aware of his physical capabilities following the recurring injury problems and he has therefore decided that is best for him to walk away from the sport.
Federer has played over 1500 matches during the course of his 24 year career.
