Novak Djokovic continues to prove he is as humble as he is brilliant as he responded to a challenge of a tennis match with none other than X-Men star Hugh Jackman.Now it might sound like a weird mismatch, but the Hollywood actor took to Twitter to ask the world number two if he wanted a game.Despite not actually having any background in tennis, Jackman tweeted: "Tennis anyone? And by anyone- I mean you @DjokerNole !"The tweet created quite a stir with near 2,000 retweets, over 13,000 likes, and numerous responses, including the man himself Novak Djokovic.Djokovic replied by saying: "Ready to fly over to Monaco for a game or two? But you cannot use your claws on the court.. or can you?"Don’t you just love the banter?Djokovic just continues to prove he is tennis’ ‘Mr Nice Guy’ and has humility despite fame.Okay, Jackman is a Hollywood star, so it’s not like Djokovic is slumming it on a concrete court at a state secondary school, but this sort of response shows that a top athlete still can have respect for others wanting his attention whilst dealing with the pressures of a high level sport.Jackman, who played X-Men hero Wolverine for the last time (apparently) in March this year, was surely not expecting any real uptake on his offer, but the Serbian tennis star has once again proven he is willing to get involved in the fun side of the sport as well as being competitive on court.

At the 2014 French Open, Djokovic’s match was halted due to rain and instead of letting the ball boy get soaked whilst he held an umbrella for him, the tennis star invited the youngster to sit down beside him and have a drink, whilst offering him his tennis racket in exchange for the umbrella.

This brought huge levels of respect from the crowd and fans around the world and showed that even huge stars can still be grounded.

The fans on Twitter went crazy for Jackman’s offer too

Even the fans were excited by this one. One replied to both Jackman and Djokovic with a picture of the actor with his famous Wolverine claws photoshopped in...or were they?

Another held out hope of umpiring the game and tweeted: "I’m at Monaco from 18 to 22 April so I can be the referee if you need."

My personal favourite though was from @FigchenK, who posted: "Game, Set & Scratch."
