Asked if he would be back next year to attempt to win a third Wimbledon crowd, Nadal replied: "I never said I not going to come back. Yeah, I want to come back because I want to play more times in the Centre Court."
"I like playing more on Centre Court," he added in the Spanish part of his press conference, per sport360.com. "Someone has to play on Centre, and it's almost always the same players here. This is the reality. Here, there are many of us who have won a lot in our careers, who have a lot of important history behind us.
"A tournament that wants to be as traditional and as special as Wimbledon has to distribute the number of matches scheduled on Centre Court and that not always the same people play there, and when there are doubts, the others are sent to other courts."
Nadal played two of his four matches on Centre Court. Murray and Federer have played all four of theirs on the main arena, while the other member of tennis's Big Four, Novak Djokovic, has played three.
Federer progressed to the quarterfinals with a straight sets win against Grigor Dimitrov and - before Nadal's match with Muller completed - noted how fortunate he was to be given the opportunity to play on Centre Court.
"Playing here on Monday on Centre Court I feel very privileged because I know they could have easily put Rafa or Novak or another women's match on centre court today," Federer said. "But they chose to put me instead as well so I'm very happy. It helps maybe to have played so well here over the years and I try to pay it back by trying to play good tennis and hopefully exciting the crowd."
Nadal's Wimbledon campaign ended following a dramatic four-hour, 48-minute fourth-round loss to 34-year-old world No. 26 Muller. The newly-crowned 10-time French Open champion and world No. 2 hadn't dropped a set - let alone a match - in two months before falling 6-3 6-4 3-6 4-6 15-13 to Luxembourg's daring left-handed serve-volleyer.
An inspired Muller blasted 30 aces and 95 winners to stun spectators and reach just the second grand slam quarter-final of his 13-year career.
Muller, who will play Croatian Marin Cilic next on Wednesday, could barely believe he'd taken out one of the game's all-time greats.
"It's a great feeling to be winning that match. At the end, it was just a big battle," the journeyman said.
"I haven't realised what's happened. I'm just glad it's over and I'm in the quarter-finals."
The epic finished just after 8.30pm local time and Muller admitted he thought he'd need to come back on Tuesday to complete it when Nadal fought back from two sets down and staved off four match points in the tension-filled fifth.
In extraordinary scenes, the chair umpire even asked fans in the back row of the arena to stand up to shield a reflection from the setting sun that was bothering Nadal as he went to serve to stay in the match at 10-11.
But there was no denying Muller as he finally prevailed on his fifth match point to join
Lleyton Hewitt and Roger Federer as the only men to have conquered the 15-times major winner twice at the same grand slam event.
Muller also toppled Nadal at the All England Club in 2005, while Hewitt enjoyed wins over the mighty Majorcan at the Australian Open in 2004 and 2005 before Federer beat his great rival in the 2006 and 2007 Wimbledon finals.
It was Nadal's fifth straight defeat before the quarter-finals on London's hallowed grass, since losing the 2011 title match to Novak Djokovic.
"I lost in the fourth round. That's not the result that I was expecting," Nadal said after falling short in his bid to complete the third French Open-Wimbledon double of his career.
"I didn't want to lose that match. So it is tough to analyse that in a positive way right now.
"I played better than other years, true. At the same time I was ready for important things, so I lost an opportunity."
