It will be interesting to see what effect Agassi might have on Novak and also if Lendl can help sort out Murray's problems. I'm surprised that Agassi is willing to spend time on the tour but maybe the draw of being involved again in the tennis world is just too much of a temptation? In his book he said that he hated tennis which I had always doubted!
Fognini has to be one of the most disappointing players on the tour in terms of childlike behaviour which is such a shame as he is capable of playing incredible tennis. He should team up with Benoit Paire of France in the doubles - a real soulmate!
In terms of winning the men's singles it's difficult to see pass Nadal but in the slams I always rate Wawrinka, especially on clay. Murray and Djokovic are just so unpredictable at the moment and Thiem is looking dangerous on the clay. No absolute clear favourite this year in my view other than Nadal perhaps?
