French Open 2021: Roger Federer, Novak Djokovic, Rafael Nadal enter fourth round of Roland Garros

Swiss tennis maestro Roger Federer on Sunday stormed into the fourth round of the ongoing French Open. Federer defeated German lefty Dominik Koepfer in a gruelling 7-6(5), 6-7(3), 7-6(4), 7-5 battle to reach the last 16 of the tournament.

The 39-year-old began well, as he served smartly. But his 59th-ranked German opponent immediately showed that the game was not going to be a cakewalk as he hit heavy groundstrokes on both wings to keep the Swiss back.

“My fighting spirit got me over the line. You’ve got to love what you do, and I do."
