Davydenko has a good shape at the end of the season, he won a very strong competitors, his game is very fast and strong. Del Potro is playing tennis in the middle, after the U.S., he played very badly and I think 1.7 is a little on him, I think there an equal chance in this game. I think the game will be long and win it Davydenko. they played three games each and two Davydenko won, I think he can win and today, after a beat Federer. good luck.
