It's been a great year for Andy Murray: a second Wimbledon title and Olympic gold, a newborn baby, and the world number one spot have come the Scot's way.
But with the ATP Tour Finals in London this week, and the Scot on top of the world, are there any chinks in the three-time grand slam champion's armour?
The short answer? yes. The long answer...
1. ATP World Tour Finals
Andy Murray goes into the 2016 ATP World Tour Finals as the best tennis player in the world for the first time ever, but he's got a pretty rubbish record in the season closer.
With a win rate of just 50%, the Scot, who has reached every single grand slam final in his career, has never reached the final here, having made the semi-finals just three times.
Perhaps the most embarrassing result for Andy came during the 2014 round robin stage, where Federer comprehensively beat him 6-0 6-1. Ouch.
2. Australian Open Finals
Novak Djokovic and Andy Murray's rivalry puts the Scot's inability to win the Australian Open into stark contrast; when Murray lost for the fifth time in a Melbourne final, Djokovic collected his sixth title.
Murray first reached the final in Oz in 2010, losing to Roger Federer in straight sets, and it set the tone. In five final appearances, Murray has pinched just two sets from his opponents.
Maybe he has half a mind on the critters down under, we're not sure.
3. Leaving history well alone
The year 1936 will get a lot less coverage now thanks to Andy Murray, who is rubbish at just letting history be. No British man had won a grand slam singles title since Fred Perry in 1936, and Great Britain hadn't won the Davis Cup since then either.
Murray changed that, winning the US Open in 2012 in a windy epic against Novak Djokovic, and helping GB to Davis Cup glory against Belgium in 2015.
He also became the first male Brit to win the Olympic tennis singles gold since 1908 when he beat Roger Federer at London 2012, before becoming the first player, male or female, to win two Olympic tennis singles golds after a marathon final against Argentinian Juan Martin Del Potro.
Andy Murray cares not for history books.
4. Looking cool at Christmas
Andy Murray just does not care what you think of his Christmas jumper. Doesn't care.
Murray's fanciful Christmas jumpers are a bit rubbish, and he's not bothered who knows it.
Ladies and gentlemen, we present to you: Andy Murray, the world's greatest tennis player.
