Panesar has the potential to be a very good Test bowler, and Vettori is a very good Test bowler.

This for me is the difference. As it is I doubt Panesar will ever match Vettori with the bat or in the field. But he should be able to match him, and over take him with the ball.

Today they go head to head in an ODI, and it is possibly the case that the spinners will win it!!
