I know the history of the Masters Cup. That my name is there is something amazing for me. He added: I was surprised it was 6-3, 6-4. Before I was playing three-set matches, pretty tough, mostly two hours. I was coming in from the first point with 100 percent concentration. I won my first serve, I started to get really good concentration, to be positive, everything was feeling good. He said some of the prize money would be spent in the Maldives but his target was finally owning a flat in Moscow. Del Potro, 21, said Davydenko had played the final with the speed of a computer game character. This tournament has a great champion in Nikolay. He worked hard to beat every player here this week. He played much better than me, and thats it, he said. He played unbelievable tennis. He beat me in good way. Hes very strong. Ive never beaten him on a hard court or indoors. Hes very fast. He plays like on a PlayStation, he runs everywhere. Its very difficult to make winners. I did a good tournament anyway, he added. Both finalists finished second in their groups.
