Should nadal learn the service motion of Goran Ivanisevic?
1. They are both lefty.
2. They toss the ball low
3. Closed stance in their delivery
4. They put lots of action to ball.
The only difference I think is Ivanisevic's serve has better disguise. But if Nadal will learn Goran's serve, he will be close to unbeatable. What do you think?
