World number one Rafael Nadal maintains he will not let the disappointment of his 2012 Wimbledon defeat to Lukas Rosol cloud his focus for when they meet again in the second round this week.
Nadal recovered from what was a spirited opening attack by Martin Klizan, ranked some 50 places below the French Open champion, to close out a 4-6 6-3 6-3 6-3 win on Centre Court.
The victory in just shy of three hours set up another showdown with Czech Rosol, who beat Frenchman Benoit Paire on Tuesday.
Rosol recorded a shock five-set win over Nadal at the same stage two years ago, but the Spaniard insists that clash will have no bearing on preparations for Thursday's encounter.
Nadal said: "I lost because he is a good player, a player that can play very well on this surface.
"He is an aggressive player, and it will be a tough match again.
"I know if I want to have chances to win, I need to play very well, that is what I am going to try.
"If not, I don't have chances to be in the third round, but I am going to fight for it."
Nadal added: "When you are in a match, you are not thinking about what happened last year, two years ago or five years ago.
"When you are in a match, you are thinking about the next point, you are thinking about finding a solution for that match.
"What is past is past. What happened, happened."
Nadal lost last year in round one to unheralded Belgian Steve Darcis.
However, the 2008 and 2010 Wimbledon champion is not about to read much into those temporary losses of form on grass.
"That's part of the sport, no?" the 28-year-old said.
"Grass is a difficult surface, a surface that I played so well on during a part of my career, so it is a surface that I really have positive results on and have in my heart, because here was one of the most important tournaments of my career.
"I am excited to be back here, to win again a match in Wimbledon, in the Centre Court.
"When you go on court and you lost last year in the first round, the year before in the second round, I'm not going to lie to anybody, sure it stays in your mind, but in the end it is just a tennis match.
"And after winning at Roland Garros, you are able to go on court with a little bit less pressure, and that helps."
Nadal feels it will naturally take some time to adjust to a change in surface, which next year's delayed start of Wimbledon is designed to try to help players compensate.
"In the beginning of the tournament, it is a little bit more difficult with the movement, the court is a little bit more slippery," he said.
"I don't have to think a lot about what I have to do when I am in the semi-finals of Roland Garros because I have all the things come together and it is automatic.
"Here, you need to adjust the movement, you need to adjust the rhythm, to find the right feeling on the speed of the ball, to find the right places to serve because the serve is so important, all the things that you need to keep doing.
"At the beginning, these things are not going that easy, after a few matches you are able to win and play with the right tactic."
