In general, I'd agree. His backhand is too weak to hang with Nadal on clay even if he's on fire. But he could definitely have at least tested this 'comeback Nadal' if he wasn't in WTA ballbashing mode today. Let's see if someone can do it (test Nadal) in Sao Paulo, draw is a bit better overall.
Yes, I wanted to see Nadal-Nalbandian, but they are in different halfs and Nalbandian will probably lose to some mug.
