"That's not a tape you want to look at," was John McEnroe's caustic view of Andy Murray's 56-minute demolition by Roger Federer on Thursday.
"If I were his coach I would definitely take a break - he needs a break."
The former world number one was not alone in being stunned by the one-sided nature of Murray's final match of 2014.
Former British number one Tim Henman described it as "a real lesson", while seven-time Grand Slam champion Mats Wilander questioned whether Murray is ready to make the necessary changes to get back among the game's elite.
For his part, Murray spoke in the aftermath of looking at his game plan and becoming "totally clear about what I want to do" for 2015.
Briton Murray described his season as testing but "fine" bearing in mind he had back surgery last September, and lost the services of coach Ivan Lendl in March.
He went on to play 79 matches, his busiest year, and racked up three titles in a gruelling six-week run at the end of the season that saw him qualify for the World Tour Finals.
However, Thursday's defeat in London was his ninth at the hands of Federer, Novak Djokovic or Rafael Nadal in 2014.
"There's clearly a gap," added McEnroe.
"Part of it is what happened leading up to [London]; he's played too much, so he's on the verge of burnout - I'm assuming without having spoken to him.
"You're talking about someone who had to play a lot to get here, so he seems to have not much left in the tank. He looked tired, his legs looked heavier.
"I don't think you can judge by one match, but overall it's been a bit of an uphill battle for him. It seems like he's not quite where he was.
"Why that is, I'm not sure. That's a question I don't know if even he knows the answer to."
Murray's crushing loss to Federer served as a sharp reminder of how far the Scot has to travel to get back to the very top of the game.
Federer, 33, recovered from his own back issue last year to enjoy a superb 2014 and end the year within sight of the number one ranking.
"The best example is Roger," says Wilander.
"He's taken it to a completely different level. He's changed racquets, he's hired Stefan Edberg to help him out with volleys, and his game is different.
"That's the scary thing, to take that first step."
