I'm being facetious i guess but i feel Murray will strike in 2009,fingers crossed any way.Swish i know you look @ tennis different from Nadal fans. All it takes is one player to make life harder for Nadal on Clay.Just maybe it could be Del Potro,fingers crossed.To me this is Del Potro best surface where others may not think so.
I haven't really paid any attention to Petro on clay, I still say Fed has the best chance of anyone on clay, he can win a set here and there convincingly but Nadal thinks very quick on his feet, makes adjustments and wins. I've never seen Fed come up with a plan B that worked but if Nadal doesn't have an answer he can lose.
This coming year has a lot of questions that won't be answered here but trying is a lot of fun.
So there's no telling what Petro may bring, one thing on his side is his height, maybe the high bounces won't bother him as much. Nadal can win a lot of different ways however so it's hard to cover all the bases on clay with him.
