Rafael Nadal is well aware of the threat posed by Juan Martin Del Potro in their fourth round clash at Wimbledon later on 'Manic' Monday.
The top seed and defending champion will be third on Centre Court when he takes on the former US Open winner, who is rebuilding his career after a serious wrist injury.
The Argentine is currently ranked 21st in the world but Nadal has total respect for the 22-year-old, whom he leads 5-3 in head-to-heads.
"I'm not lucky to play against Del Potro in the round of 16," Nadal said. "But that's what it is and I have to be playing my best tennis to try to win.
"His game has everything. I think he has a good serve, very good shots from the baseline.
"He's complete. I think he's a complete player."
However, Del Potro knows he must improve on his current form to cause a major upset.
"We played this year in Indian Wells and he won really easily," Del Potro said.
"I don't know if I'm still far away from that level. He's the number one and he will be the big favourite. In the fourth round, all the players are tough.
"I don't know if I will have a little chance or not, but I will try to make a good game."
After a stop-start opening week at SW19 officials are hoping to play every fourth round match in both the men's and women's draws on 'Manic' Monday.
