Positioning in a rally

I have a typical problem that need to be solved. 

During matches my opponent does a side topspin which reaches almost the net. It goes a right curve. And I am always too slow to reach the ball. Also cross steps and shuffles doesn't help. So what can I do instead? 

Maybe I should predict players movement or which options do I have?

Hi Malke,

Think about your positioning when he is playing the stroke.  You need to be able to cover the possible angles that he has.  So if he is wide on his forehand then you need to move to a wide position on your forehand before he hits the ball.  As soon as you see he is going to hook the ball with sidespin, then you can move even further to your forehand side.  This should allow you to get into position a bit earlier.

Of course you should still work on your footwork movements as well to try and get them faster.
