Juan Martin del Potro has expressed his excitement ahead of facing Novak Djokovic in the semi-finals of Wimbledon.
The Argentine is yet to drop a set in the entire tournament and came through with a 2-6 4-6 6-7[5] victory over world number four David Ferrer on Wednesday.
While he admits that facing the world's best player will be a big challenge, Del Potro insists that he is up for the fight against Djokovic.
"I will need to be 100% or 110% against him," Del Potro told the official Wimbledon website. "He's the number one. He's a former champion here. It's going to be a more difficult match for me like today. But if I'm okay, if I do everything good to be ready for my next match, I will be excited to play against him.
"I remember the match during the Olympics last year on the same surface. But this time the pressure is different, I know. But I will try to be ready and do my best."
Andy Murray will face Jerzy Janowicz in the other semi-final on Friday.
