Roger Federer believes the ATP and WTA tours should be merged in order to ensure tennis emerges stronger from the coronavirus pandemic.

The 20-time grand-slam champion posted a series of tweets expressing his belief that the sport would be better off with one stronger governing body.

Federer feels that the time has come for tennis to be "united" and his idea received widespread support.

The 38-year-old's comments attracted support from his fellow professionals, including 19-time grand-slam winner and long-time adversary Rafael Nadal.

Billie Jean King, who won 39 grand slam titles, said it was an idea she had been proposing since the 1970s.

Reigning Wimbledon women's singles champion Simona Halep, former Wimbledon champion Garbine Muguruza and ATP star Diego Schwartzman also tweeted their support.

The tennis calendar has been decimated by the pandemic, with Wimbledon forced to cancel and the French Open postponing their grand slam event until September.

All tennis is currently postponed until at least 13 July.
