World No. 2 Andy Murray admitted playing the other member of the "Big Four" is a tough task to accomplish.
Murray has found considerable success this season, having reached the final round of two Grand Slam events and seemingly finding his niche to become a consistent contender in the tennis scene. However, the Scot confessed he is still having a hard time playing Novak Djokovic, Rafael Nadal and Roger Federer.
"Novak has improved his volleying, but Roger and Rafa are also two of the best volleyers. Novak returns exceptionally well. In those matches, everyone does everything well. It's not like there's loads of weaknesses to exploit. It takes time to work things out and also to find a weakness," Murray said, reports Tennis World USA.
Murray has dueled each of the three tennis stars many times since turning pro in 2005. While the 29-year-old has been the ultimate underdog when playing either of the three, Murray seems to have found a way to level with Djokovic, Federer and Nadal this season.
Murray, who has only met Nadal in a match twice this year, lost to the King of Clay in the semifinal round of the Monte Carlo Masters. But Murray was quick to level their matchup defeating Nadal in straight sets in the SF stage of the Madrid Open.
On the other hand, Murray has yet to battle Federer this season, partly because of the Swiss Maestro's struggle to remain healthy that forced him to be sidelined for more than two months. Their last five outings have not gone well for Murray, although it could be a different story when the get the chance to face each other this year, with the two-time Grand Slam winner gaining steam.
Meanwhile, the most interesting rivalry in the sport forming today would probably be between Murray and Djokovic .
This year, Murray has already faced Djokovic four-times, including two Grand Slam finals appearances, most recently at the French Open. Murray's lone win, so far, against Djokovic only came at the Italian Masters in Rome, stunningly beating the Serb in straight sets.
At Wimbledon, Murray will have a chance to face Djokovic and Federer, but only in the final round of the tournament, with the Scot in the other half of the bracket.
With Djokovic's continued dominance and Federer getting back in full health, it would be tough for Murray to win against either of the two in Church Road. However, winning against Djokovic and Federer would only establish himself as true rivals to other members of the Big Four.
