Novak Djokovic is currently the best tennis player in the world, and he has been hanging around with arguably the world's best football team recently; is there anything he cannot do at the moment?
Real Madrid are currently enjoying a break from their La Liga campaign, owing to the league's winter break, but they have still had time to showcase their skill in a friendly competition, following their trophy-win at the Fifa World Club Championships.
'Los Blancos', featuring the likes of Cristiano Ronaldo and Gareth Bale in their squad, took to the field for a friendly against AC Milan in the 'Dubai Football Challenge trophy', but they ended up on the wrong-end of a 4-2 loss.
Their defeat was lightened up, however, by Djokovic's half-time appearance in Dubai. He enjoyed trying some trickery with Bale.
The crowd applauded the tennis star as he showed his prowess with the ball at his feet, while Bale's fellow Real stars Pepe and Toni Kroos were also pictured with impressed looks.

The Serbian star, who is a fan of Milan, as well as his local club Red Star Belgrade and Benfica, will have been happy with what we saw from the Italians. Stephan El Shaarawy's double, along with further strikers from Jeremy Menez and Giampaolo Pazzini, were enough to down the reigning European champions for whom Ronaldo and Karim Benzema both netted.
Djokovic will be hoping that Milan's success will rub-off on him as the 2015 season draws nearer.
The 27-year-old is comfortably the world's number one, having won the ATP World Tour Finals in November, he'll be hoping to keep that sort of form going when he appears in the Australian Open in January.
The major in Melbourne is Djokovic's most fruitful; four of his seven Grand Slam titles have come from Down Under. It won't be a walk in the park for the Serb, however.
Traditional on-court enemy Rafael Nadal is set to return from the various injury that curtailed his 2014 season. The Spaniard has only ever won the Australian Open once, and will therefore be looking to improve that record as he chases Roger Federer's record all-time Grand Slam haul of 17 titles.
Federer himself, however, will surely have something to say about Nadal surpassing him. The Swiss veteran, now 33-years-old, hasn't added to his collection since 2012 but experienced a great form revival over the last few months.
It won't be long before the battle begins... Who will have the happiest New Year?!
