French Open champion Rafael Nadal will face his 2012 Wimbledon nemesis, Lukas Rosol, on Thursday, knowing he will have to up his game to avoid another second-round exit at the hands of the Czech world number 52.
After a first-round defeat at the All England Club last year, and failure at the same stage at Halle two weeks ago, the world No.1 ended a three-match grasscourt losing streak with a nervous four-set win over Martin Kilzan on Tuesday to set up the Rosol rematch on Centre Court.
"He's a player that can play very well on this surface," Nadal, champion in 2008 and 2010, said.
"I lost (in 2012) because he's a good player. He's an aggressive player. I know if I want to have chances to win, I need to play very well."
