Roger Federer has revealed he faces “many months” out of the game as he prepares to undergo further knee surgery.

The 40-year-old, who missed the Tokyo Olympics with a knee injury after losing in the quarter-finals of Wimbledon, said he had opted for another operation to give himself “a glimmer of hope” of returning to competition.
