1. Murray has fantastic returns and causes Federer to play more balls than he prefers. Federer has even started double faulting with each match he plays Murray - signs that Fed is going for more on 2nd serves. 2. Federer has huge dips in his 1st serve percentage against Murray. Federer usually starts at 64% but often in sets 2 and 3 vs Murray in the last few meetings he go's down to below 50%. 3. Murray serves very well nowadays and with a lot of variety and placement. He has also found a weakness on the Federer fh return which is currently giving Murray a ton of free points. 4. Murray can handle the Federer bh slice and gives Federer a lot of his own medicine with his own effective slice both down the line and crosscourt. 5. Murray can breakdown the Federer bh in a variety of ways. Murray uses flat, spin, loopers and topspin to breakdown the Federer bh. 6. Murray can move as efficiently as any of the top movers on court. This makes life hard for Federer as it is very difficult to overpower Murray due to his nimble movement and great hands. 7. Murray's bh is so solid on bh to bh exchanges and wins most of their cross court exchanges. 8. Murray is 6 years younger than Federer and is hungry, determined and full of beans. Murray wants success at any cost and is motivated to achieve all his goals,Which, as he puts it '.it's all about winning slams'. When combine all the above you have a unstoppable package that will trouble any top player at any given time. The only player that could match the considerable talents of Murray in Federer's generation was Nalbandian and it is no secret that Nalbandian always gives Federer a run for his money. Unfortunately, for Nalby he never put himself in enough positions to meet Federer in the big grandslams on a consistent basis. I get the feeling Murray wont make that mistake. Thoughts?
