In this good match, i think that Juan Martin Del Potro is better than his opponent.He has a very good serve, and very strong and fast.Andy Murray he is not so good on the clay, he is better on hard.But here it's Madrid and it's clay, where Del Potro is better than Murray.Yesterdau Del Potro make a very good victory on Stanislav Wawrinka wich has a very good form, but Del Potro was the best.Today I think again he will be the best.
