Murray, who claimed his second Wimbledon title with a 6-4, 7-6 (7/3), 7-6 (7/2) victory, looked remarkably fresh faced considering he was photographed leaving a nightclub at 3.30am the night before.
The newly crowned two-time Wimbledon champion said his body felt fine after he beat Milos Raonic in straight sets to lift the trophy on Sunday, but he had previously cited his heavy playing schedule as a consideration.
Andy Murray has warned world number one Novak Djokovic his best is yet to come as the Scot aims to follow his second Wimbledon crown with a sustained run of success.
It also helped him forget the disappointment of losing the Australian and French Open finals to Djokovic this year.
"If I want to add to three slams, I'm going to have to find ways to win against them", said Murray.
Murray pulled off one of his most unexpected feats by leading Britain to their first Davis Cup title in 79 years last year.
Andy Murray was rightly awarded with a Wimbledon trophy - the second of his career, for being the best player at this year's championships. "I've just got hay fever".
In 2013, Murray famously ended Britain's 77-year wait for one of its own to win the men's final at Wimbledon, a quest that became burdensome. The pair split in 2014 but are looking a powerful double act once again, ice man Lendl the flawless soothing influence for the often hot-headed Murray. "I'm going to try to get myself back in this position, try to be better in this position".
He added later: 'I still feel like my best tennis is ahead of me, that I have an opportunity to win more [Grand Slams].
"I think before, when I won here, I was motivated by the Slams and my results for the rest of the year showed that".
Andy was awesome and played so well from start to finish against Milos Raonic, dominating the final.
"Failing's not bad. I put myself in a position all of the time in these events to win them".
World number one Novak Djokovic will also be missing from the quarter-final tie, which will be played on clay.
Murray took time out to speak with members of the Wimbledon ground staff and shook hands with supporters as he posed for photographs.
"I've made the finals of the last five tournaments and I've never done that before".
"The Olympics is important to me", the Scot told BBC television.
With Djokovic's phenomenal winning streak coming to an end as wells as Roger Federer and Rafael Nadal being well off their peak performance, some believe this victory might herald a reshuffle within the so called "Big Four" tennis stars in which Murray can claim a bigger piece of the tennis pie.
His hero Andre Agassi won Olympic gold and eight Grand Slam singles titles, including five from 29 - the same age as Murray now.
World number seven Raonic said: "We haven't spoken about anything, but I'm sure we're going to have that discussion over the next 24 hours". Everyone's time comes at different stage.
'But I'm going to speak to him this afternoon.
