Rafael Nadal: "I played much better"

Rafael Nadal has said that he played "much better" in his win over Dudi Sela in the third round of the Australian Open this morning.

The third seed struggled with cramp and dizziness in a four-hour five-set encounter in the second round, but got past the Israeli player in straight sets today.

Speaking on court at the end of the match, the Spaniard said: "The last match was one of my toughest moments on court. I was lucky to [win]. It's difficult to compare. I played much better."

Nadal will face South Africa's Kevin Anderson in the fourth round.
