IMO Barcelona may win by 1 or 2 goals but of course anything can happen in football, Juventus are good at defending and they are sure to try not to accept a goal so it should be exciting..
Juve might be good at defence but they're missing Giorgio Chiellini remember. I think it will be around 3-1 or 4-1 to Barcelona. I think Barca will get a few goals at least but we could see more. I think Juve were lucky to get as far as they did to be honest.
