#4 The confidence factor
Nadal is a great frontrunner, but often takes time to get into his rhythm. Moreover, he prefers to get as many matches under his belt as possible to be match- and tournament-ready.
While he might be at home playing on clay, it is imperative that he feels good about his movement and form before he steps foot in Monaco. It remains to be seen how many matches Nadal will play in Valencia, but even a win or two will surely lift his confidence and propel him to bigger things in the months to come.
Beating Nadal on clay is no mean task, let alone beating him in a best of five sets encounter. While it is possible for someone to play attacking tennis and shock Nadal, doing it over a period of five grueling sets will be a Herculean task.
Given his comfort level on the surface and the time it allows him to get into his stride, it is difficult to see any German player beating Nadal in Valencia. And that can only bode well for the Spaniard's confidence heading into Roland Garros.
