"At this level it can come down to just a few points here or there. Probably my biggest chance was at the beginning of the second set; didn't quite get it," said Murray, who held three break points immediately after winning the first set tie break but failed to take what might have been a decisive advantage.
"When Novak had his chance at the end of the third, he got his."
While Murray received treatment between the second and third sets for a gruesome-looking blister, he was adamant that it had not been a factor.
"It had no bearing at all on the result," insisted the 25-year-old.
"It's just a bit sore when you're running around. It's not like pulling a calf muscle or something, it just hurts when you run, but it's not something that stops you from playing.
"With how physical the game is just now, that's just part of it."
Instead, Murray looked on the positive side of the final. In 2010 the Scot was left crying openly on court after losing the final to Roger Federer, but he was still buoyant after this year's final - despite the waterworks once again flowing in the press conference.
"There's going to be some obvious reasons for me feeling a little bit better," said the British number one as he wiped away the tears.
"The last few months have been the best tennis of my life - I made the Wimbledon final, won the Olympics, won the US Open, I was close here as well. It was close.
"I know no one's ever won a Slam, the immediate one after winning their first one. It's not the easiest thing to do and I got extremely close.
"So I have to try and look at the positives of the last few months, and I think I'm going the right direction.
"This is the first time I've beaten Roger (Federer) in a Slam over five sets.
"I think I dealt with the situations and the ebbs and flows in that match well. I felt much more comfortable on the court today than even I did at the US Open, so that has to be a positive."
Murray was upset to have become distracted by a falling feather while hitting a second serve at 2-2 in the second set tie-break, a moment which saw him hesitate and then produce just his third double fault of the tournament.
"I could have served. It just caught my eye before I served," he said.
"I thought it was a good idea to move it. Maybe it wasn't because I obviously double faulted."
