A listless Novak Djokovic made a shock exit at the French Open on Saturday, while Serena Williams provided more fireworks by labelling her opponent a “cheat”.

The fourth-seeded Serb, tipped as the man who could deny Rafael Nadal a record fifth consecutive title after snapping at the Spaniard’s heals throughout the claycourt season, instead became the biggest name to tumble out.

Djokovic hopes were snuffed out 6-4 6-4 6-4 in the third round by Germany’s Philipp Kohlschreiber before women’s second seed Williams created some drama of her own.
