After watching Sania play, I felt that she could become a top 20 or top 30 player but that's it. She doesn't have the game to beat the best. If she drastically improves her serves, holds her nerves and moves better on court she might be a top 15 player. She just hasn't got enough firepower to beat Sharapova. If she goes for more, Sania's bound to have more unforced errors. Unlike her, Sharapova on the other hand is more solid. She is bigger, stronger, has an excellent serve with brilliant groundstrokes. At the same time since Sharapova is such a good mover on the court she can also run a few balls down and play a defensive game as well. Probably's that's why she's no 1. Oops and I almost forgot....Sharapova is soooo hot as well!
