That is why don't judge players based on their ranking. We should judge them by seeing their play. I decide this match based on Nadal ranking, and I lost my bet. I think Nadal career is going to end.
For those that dont know this, nadal's career has ended like a years ago when he keep on failing to win. Djokovic and murray on the other hand is still very good despite that djokovic lost to del potro, I guess he underestimated del potro too much and now he suffer because of this and murray learned some lesson from this
