This is Roger Federer's tournament, and he will win it again, there is no question about it, but today he'll have a tough nut to crack. Marko Chiudinelli is a great player, or better was a great player, and he is coming back with some nice scores recently. He can win one set, but I really don't think he will.
In my opinion he will get to a tiebreak in one set, and lose the other one with one break (7:6 6:3).

Good luck!
