“This tournament has a great champion, like Nikolay. He worked hard to beat every player here this week. So maybe I have to improve a little bit the little things. But he played much better than me, and that's it. He played unbelievable tennis. He beat me in a good way. He's very strong. I never beat him on hard court or indoors. He's very fast. He plays like PlayStation. He runs down everything. It is very difficult to hit winners. But I think he is a great champion. Nobody knows how we can beat him.”--Juan Martin del Potro
