Nice to see you got a new keyboard.
You can say any genuine contender "wont" win it and more than likely be right because it is a knock out competition and a game over two legs can be won by anyone.
Personally i wouldn't say Barca "wont" win it, i think they have a better chance than most and it'll most likely be Barca, Cheslea, United or Inter that pick it up depending on the draw.
EDIT: My big outsider would probably be Arsenal, they have proven that they can raise their game by beating United and Chelsea already so if they raise their game in europe they can match anyone. However i pray Liverpool get nowhere near it this year.
