WATCH: Novak Djokovic breaks into Phil Collins song and dance after US Open win

Just the two majors out of three and it's crisis central in Novak Djokovic's world.

The Serbian's third round exit at Wimbledon still has questions circling around his form despite having already accrued the Australian and French open titles already. Personal issues, injuries, coaching problems have all been thrown into the mix so you can forgive the Djoker for staying tight-lipped in interviews - or whatever the exact opposite to tight-lipped is (it still had the same effect). The world number one advanced in four sets past Jerzy Janowicz in his US Open first round. And, rather than answer questions he didn't want to answer, Djokovic just burst into song instead. Phil Collins would be proud. https://twitter.com/CauldronICYMI/status/770459556778344448 We're awaiting Andy Murray's response. The new GAA Hour football podcast is out.
