Seven-time champion Roger Federer eased into the last eight of the men's singles at Wimbledon with a commanding straight-sets win over Tommy Robredo.
The fourth seed lost to the Spaniard when they met at the 2013 US Open.
But Federer reigned supreme against a player who had never made it past round three in his 12 previous visits to SW19, winning 6-1 6-4 6-4.
Federer's quarter-final opponent will be fellow Swiss Stan Wawrinka, who beat Spaniard Feliciano Lopez 7-6 7-6 6-3.
The Australian Open champion, seeded five, prevailed in an ill-tempered encounter that ended with the players having a heated debate.
Also through to the last eight is Canadian eighth seed Milos Raonic, who was a 4-6 6-1 7-6 (7-4) 6-3 winner over 10th seed Kei Nishikori from Japan to reach his second consecutive Grand Slam quarter-final.

|"That was virtually flawless by Federer. He did everything well - he timed the ball well, served impeccably, came to the net, chipped and charged and showed a lot out there. Is he now ready to be a challenger for these championships? Maybe."|
But Federer, 32, is relishing the chance to take on his fellow countryman, who he has beaten in 13 of their 15 encounters.
"It will be amazing to play Stan in the quarter-finals here, hopefully on Centre Court, because things like that don't happen too often in Swiss sport," he said.
"I'm pleased with the way I am playing. I'm moving well, serving well and doing all the things right that you need to be doing to go deep into this tournament. I feel my game is right there.
"The important thing is to keep it up and not have any let-downs for five or 10 minutes when you are not feeling quite right.
"I am healthy, things are where I want them to be, but the quarter-finals is really where the tournament starts."
Wawrinka, who has reached the last eight at SW19 for the first time, concedes that playing a fully fit and confident Federer at Wimbledon is "one of the biggest challenge in tennis", although he beat the former world number one the last time they met, in the Monte Carlo final in April.
"It's like playing Rafa in the French Open," he added. "When you go on court, you need to trust yourself, you need to go for it."
