World number two Andy Murray played down the pressure on him to win the Wimbledon title for a second time.
With Novak Djokovic out, he is favourite to claim the crown at the All England Club ahead of a quarter-final meeting with Jo-Wilfried Tsonga.
Murray became the first British man since Fred Perry in 1936 to win Wimbledon when he took out the event in 2013.
The 29-year-old believes the pressure on him has changed thanks to that - his second grand-slam title.
"It's totally different now because I've won Wimbledon so the pressure isn't the same," Murray said.
"At the time it had been such a long wait that everyone saw that as being my chance to win Wimbledon and I've done that now.
"So, obviously I want to do it again but the pressure - you can't compare the pressure this year to when I played Novak a few years ago."
While Murray faces Tsonga, Roger Federer, Marin Cilic, Milos Raonic and Tomas Berdych are among those also in the last eight.
Murray believes there may be others seeing a chance, particularly those yet to clinch a major trophy.
"I've won grand slams before," he said.
"I think for guys that haven't that are still in the draw, they're looking at it and seeing an opportunity for themselves.
"You saw it a little bit with matches on Monday. You know, maybe upsets potentially. Milos in his match went a couple of sets down - I think for the guys in that part of the draw, they are seeing a big opportunity."
