Rafael Nadal after his win over Juan Martin Del Potro:
"I think it was great quality tennis, the final set was there were some amazing points. Sorry to Juan Martin, an amazing opponent and player. In some ways he deserves to go through too.
"Anything could happen, so this is a big achievement for me to get to the semi-finals at Wimbledon.
"The last set has a little of everything, great points, great rallies, he was hitting crazy with his forehands. I tried to resist, maintaining focus.
"Now is the moment to enjoy but start to recover, it was a tough physical battle. the opponent that is coming one of the toughest. I am just excited to be in the semis. I need to recover to give my best.

It was such a great effort from Del Potro. After losing the first set we thought he would be up against it but he did well to get on level terms and then get his nose in front.
It was Rafa's resilience, his intensity to find a way to come out on top.

There's a choice for Del Potro to make. Does he go for it, take his chances with the forehand or put balls back in play and make Nadal work for it? Does he make Nadal think about it? I think he has to go for it.
