Andy Murray faces a tough battle to reach the Wimbledon final again this year.Murray - who will take on big-serving German Benjamin Becker in the first round - Roger Federer and Rafa Nadal are all in a brutal bottom half of the draw.But Murray has at least avoided the worst case scenario of facing Nadal in the last eight. Instead, Nadal is likely to face Federer in a mouth-watering quarter-final, with Murray their probable semi-final opponent.If the draw goes according to seedings, Murray will face Janko Tipsarevic in the last 16, Jo-Wilfried Tsonga in the quarter-finals before taking on either Federer or Nadal.The quarter-final draw would be Novak Djokovic v Tomas Berdych, David Ferrer v Juan Martin Del Potro, Nadal v Federer and Tsonga v Murray.The biggest winner is Djokovic, who could be facing a semi-final against clay court specialist Ferrer. His biggest rivals - Murray, Nadal and Ferrer - are all in the other half of the draw.None of the top five seeds should be troubled in the first round.Murray beat Becker 6-4 7-6 (7-3) at Queen's last week, and assuming he gets past the big-serving German, he could face another Briton, James Ward, in the second round.Tommy Robredo, the experienced Spaniard, could be next before things become decidedly difficult with Tipsarevic, although the Serb has had a bad year by his standards.Djokovic opens up against Germany's Florian Mayer in the first round. Nadal takes on the Belgian Steve Darcis. Ferrer - the fourth seed and beaten finalist at the French Open - plays Martin Alund and Federer will face the veteran Romanian Victor Hanescu.More to follow...
