David Ferrer installed Andy Murray as favourite to win their quarter-final clash at Wimbledon but believes the weight of expectation behind the Scot could hamper the home hope.
Spanish seventh seed Ferrer booked his place in the last eight with a routine straight-sets win over Argentina's Juan Martin del Potro under the roof on Centre Court.
Ferrer dominated against the ninth seed, who was briefly treated on court with a knee problem, to win 6-3 6-2 6-3.
The 30-year-old will face Murray, who defeated Croatian Marin Cilic in straight sets in a rain-interrupted match, on Wednesday.
Ferrer has beaten the British number one in their last two matches. The most recent was at the quarter-final stage of the French Open last month.
However, the pair have never faced each other on grass and Ferrer suspects the pressure placed on the Scot could be a telling factor.
"Of course it is a very important match because it is the quarter-final of Wimbledon but I will try to focus on every point," Ferrer said.
"I don't want to think about the people, about the expectation around this match.
"Maybe he has more pressure than me because he plays at home with your people.
"I played him four weeks ago on a clay court and now I will play with him on a grass court.
"He's the favourite player (to win) because he's better than me, and tomorrow I will try to do my best. I will have to play my best tennis to beat him.
"It's very difficult to beat Andy on all surfaces, but on a grass court it is more difficult."
Ferrer's passage to the quarter-finals, the first time he has made it to this stage at Wimbledon, has also seen him beat Dustin Brown, Kenny De Schepper and Andy Roddick to leave him the last Spaniard in the draw.
His progress to the last eight is the latest step in what has been his most successful year to date, after he reached the quarter-finals of the Australian Open and the semi-final of the French Open.
Ferrer believes hiperformance against Del Potro is up there with his best on grass as his form is hitting an upward curve.
He said: "I am trying every year to improve my game.
"I had very great years in 2010, 2011, and this year also.
"Today was one of my best matches on this court, sure, but I'm not sure if is my best or not.
"My return is my best weapon on a grass court, because on grass I don't have real power with my serve, but I am playing very well with my return.
"Of course, in this season, grass court, today it was the best match."
