I am extremely disappointed, as I have always enjoyed playing Tennis Masters Cup and had a great time in Shanghai in 2002,
To come through these situations is very important because Davis Cup can make or break guys' careers in a lot of ways.
With my baby due in the next two weeks, it is not possible for me to come. I wish the event well and am sure it will be a great success and I hope to qualify for next year's Masters Cup in Shanghai,
Especially big ties. When we've played the finals before, quite often I'd played the Masters Cup and the whole indoor circuit and a lot of matches and maybe I was physically run down a little bit going in,
That's all my focus is on, on Ferrero on Friday, and I've probably been given the opportunity in this tie to crack the whole Davis Cup final wide open on day one.
