Roger Federer was clearly one of those kids at school that was annoyingly good at any sport he put his mind to. Probably one of those that you wanted to be like, but instead had to put up with secretly envying them.
As the clock ticks closer to the start of the ATP World Tour Finals at London's O2 Arena, Federer - possibly the greatest ever tennis players - has been watching events in another sport that he probably could have been a world beater in.
He was spotted in London on Tuesday night, slightly north of where he'll be competing next week, as the 33-year-old took at a seat at the Emirates Stadium for Arsenal's Champions League encounter with Belgian outfit Anderlecht.
Although a rarity, the Swiss legend has let leads slip on-court in the past, but surely he hasn't experienced anything like what happened to his hosts that night.
With a comfortable 3-0 lead against lesser opponents, Arsenal looked like they were cruising into the Champions League knockout phase until a dramatic late meltdown saw them end the game on even terms.
Against a backdrop of some disgruntled Gunners fans, Federer may have realised at that point he had chosen the right career path; nobody boos Roger Federer!
In his younger years as a sports whizz, it has been recalled that he could have gone on to be a professional footballer. He still retains a love for the sport and supports FC Basel, who are also competing in Europe this season alongside Real Madrid and Liverpool.
"I think I made the right decision to go with tennis, even though I think football is a great sport with great crowds everywhere you go,” he said to the ATP of his correctly-chosen career path. “I would have loved to be successful in soccer too, but I'm happy I chose tennis in the end.”
It couldn't have gone any better Federer with a racquet. Just look at the build-up statistics to the ATP Finals; he's 33, aiming for his seventh title in the season-ending competition, and still has a chance of ending the year at world no.1.
He's comfortably the most successful player the game has even seen; his world record 17 Grand Slam titles represent that, not to mention his huge Finals and Masters hauls from down the years.
Despite boasting a CV which would already compete with any other famous sportsperson from any given point in history, Federer is still keen for some more silverware next week.
A terrific second half to 2014 has seen the world no.2 get to the final in all but two of the eight tournaments he has entered, a run which gives him cause for optimism heading into the O2 Arena.
WHAT NOT TO DO
He was defeated by Milos Raonic in last week's Paris Masters, but will have the opportunity for revenge when they meet in 'Group B' next week. For the time being, however, Federer is happy to relax whilst watching Arsenal squandering three goal leads.
"I enjoyed it a lot,” said Federer after the match. “It's always a pleasure going to see other sports around the world. It's a beautiful stadium with a great team and Champions League football is a big deal. I'm fortunate to be in the city right as it's happening.”
The tennis superstar will just have to hope the major crisis which affected Arsenal doesn't find its way into his own matches in London!
