Do you think Gael Monfils has a good chance at upsetting Roger Federer today?

Gael Monfils is a very talented rising star, unfortunately beset by injuries recently, but is healthy again. Roger Federer has shown that he is not as invincible as he once was, especially of late. Does anybody want to make a prediciton here?
Rafanadalgirl and Gina D, I like the fact that you’re going out on a limb and picking Monfils.
