Sylvia is a bad match up for Fedor.
The same problem nog had, is going to be the same problem fedor has. How is Fedor going to bring the fight to the ground. From what I have seen in his fights, he mostly uses his upper body to control his opponent. Thats going to be pretty difficult against a guy like Sylvia. So the question is, will he stand and can he outstrike him. Fedor has better standup, but he doesn't have the same reach.
That being said, fedor is god, so I know where my money will be lying on the table.
PS. I hate sylvia and am not excited for this fight, because Sylvia can make the most exciting fighters boring as hell. Except Randy.
