Rafa loses a few matches here and there, sure, but there are a few that I think really mean something to him - losses to Nalbandian, losses to Soderling, and that Australian Open 2008 loss to Tsonga.Not that Rafa has a personal problem with Tsonga or anything, but I think that loss really messed with his head, and no matter how many times he beats him, that loss hangs with him.
