Novak Djokovic has been unstoppable this year at Wimbledon, and if Juan Martin Del Potro is to stand any chance of getting past the world number one in the semifinals, he will have to put on a performance similar to the one against David Ferrer in the previous round, if not better.
Del Potro was in his elements against Ferrer, and despite suffering a fall which seemed to aggravate an already badly injured knee, the number eight seed, barely allowed his opponent a chance, wrapping up the quarterfinal in straight sets.
The Argentine, who beat Djokovic in the bronze-medal match in the London Olympics last year on the same courts, knows he will need to be at 100 percent in all aspects yet again to get past Djokovic.
"I will need to be 100 percent or 110 percent against him," Del Potro said after defeating Ferrer on Wednesday. "He's the No. 1. He's a former champion here. It's going to be more difficult match for me.
"But if I'm okay, if I do everything good to be ready for my next match, I will be exciting to play against him. I remember the match during the Olympic last year on the same surface.
"But this time the pressure is different, I know. I know it. But I will try to be ready and do my best."
Djokovic has been on a brilliant run since the start of this tournament, and continued that form against Tomas Berdych in the quarterfinals, rarely allowing the Czech to dictate points and eventually overwhelming his opponent with ridiculous ease.
The Serbian, who has reached the Wimbledon semifinals without dropping a single set for the first time in his career, will have some kind of revenge on his mind when he squares up against Del Potro, after losing out on a medal to the Argentine in the Olympics last year.
"I lost to him for bronze medal here," Djokovic said. "Was close match also. DelPo is a great player. I have a great respect for him. He's a Grand Slam winner.
"He struggled with injuries in last few years, but every time he comes back he comes back very strong because he just has this talent, you know, and qualities as a player.
"He's very tall, so he uses that serve as a powerful weapon. And of course forehand, that is his signature shot.
"You know, it's semifinals, so everything is open, on the table, and we both want to win."
