Defending champion Novak Djokovic showed his supreme powers of recovery once again to come through a five-set marathon against Francisco Cerundolo and reach the French Open quarter-finals.
Serbia’s Djokovic, 37, looked hampered by a leg injury before winning 6-1 5-7 3-6 7-5 6-3 against Argentine 23rd seed Cerundolo.
For the second time in three days, the 24-time major champion fought back from a two-sets-to-one deficit.
"At one point I didn’t know if I should continue," said Djokovic, who attributed the injury to the slippery clay surface.
The fourth-round match with Cerundolo started about 4pm local time on Monday, little over 36 hours after his previous contest against Lorenzo Musetti finished at 3:07am on Sunday morning.
