Rafael Nadal gets the opportunity to avenge one of his career's most humiliating defeats when he faces Lukas Rosol for a place in the Wimbledon third round on Thursday.
Two years after the unheralded Czech sent Nadal crashing to a shock second round loss, the pair meet again at the same stage of the tournament with the two-time champion Spaniard aware that Rosol poses a serious threat to his hopes of progressing towards a 15th major.
"Rosol is a very dangerous player, very strong, very powerful shots from the baseline and I know I have to play very well if I want to have chances to win," said Nadal, whose second round exit in 2012 was followed by a first round loss in 2013 to Belgian journeyman Steve Darcis.
Rosol was 100 in the world when he stunned the Spaniard two years ago; now he is 52 although since his famous triumph at the All England Club he has managed to win just three more times at the Grand Slams.
"What is past is past. What happened, happened. We don't want to change that. The only way to try something is try to change what's happening right now," added Nadal, whose loss to Rosol sparked a seven-month injury lay-off from the tour.
Rosol he will have nothing to fear from Nadal and was confident of pulling off another upset when they open playon Centre Court.
"It's Nadal who has to win, I have nothing to lose," Rosol told Czech media at Wimbledon.
Although Nadal gained a small degree of revenge at Doha this year with a comfortable straight sets win, Rosol believes his rival is at his most vulnerable in the early rounds.
"Nadal is the king of clay," he said in deference to the Spaniard's nine French Open titles.
"But he is more vulnerable on other surfaces, especially grass. If you want to beat one of the big stars at a Grand Slam, the early rounds are the best."
