Basically China has to take advantage of the suspensions Fiba gave the greeks, and Bourouris who is not 100%, and strike them in the paint, trying to get the remaining big men Greece has in foul trouble.
Wang and Yi have got to play to their size and rebound the ball, also China has got to put their best defenders on Diamantidis and Spanioulis.
Greece on the other hand, should need of Tsartsaris to shoot the ball alot in case the guards are getting covered. Also, Greece needs to shoot the ball well from outside. On defense they have to go for the steal every chance they get, as China is not a good ball handling team.
