I think 2010 will be a tremendous year for the great roger federer. Just take a look at what he has to prove. First off Federer has a chip on his shoulder after losing to Juan Martin Del Potro in New York. You see, Federer will be proving everyone wrong by winning the calendar slam. Heres why. 1. Nadal on the decline. His knees and ankles are suseptible to injury. Take a look at why Nadal has got to where he did. He plays like a tiger, always attacking and "giving his life" for every point. Nadal has to remember that tweaking a knee or an ankle is a real possibility. 2. Players like Djokovic and Murray, the so called "challengers" of Federer have fallen off. You no longer see Murray or Djokovic really breaking federers serve. Call it like you see it but murray and djokovic can only move down in the rankings, not up. 3. Up and comers like Del Potro and Tsonga dont have the shotmaking Federer has. Del potro beat Federer by pushing him back vertically. By hitting it harder and harder. Federer is the chameleon. He can adapt to that kind of style at all costs. Federer can become an all arounder all the way to a defensive basliner to a serve and volley specialist. If Del Potro wants to try to push federer around, it is not reasonable because Federer hits it harder. You dont want to get into a baseline game with Federer. 4. Sufaces are irrelevant now. Todays players are basically one dimensional on the surfaces. Nobody really can change their game now, Just look at the results, theres not too many surface specialists anymore. Federer can exploit anyone on any surface because his game cancels out their preferences. Look at why Federer is on top. He has played the surfaces better than anyone all around. Federer is going to have a big 2010. I cant see anyone keeping up with this guy. Then again who ever did. A lot of guys of 2009 were a flash in the pan. Federer will adapt again and seems to get a lot better with age. He is smarter and healthier, Look for federer to cash in on a big 2010.
