I am not saying Malaga will win, I would like them to win but they are the clear underdog. The more La Liga teams that make it through (minus Real of course), the better.
In terms of Bayern vs. Juve, look at the Bayern numbers for the UCL games vs. what they have done in the Bundesliga. When you do that they look way less impressive. In addition, they haven't really played any strong teams that will make them the clear favorite. Their group was easy, they faced a beat up Arsenal team that has been iffy all season. I just think that people have been giving Bayern too much praise and it will show once Juve and the massive amount of experience they have comes to town.
Look at what Juve have before making Bayern the clear favorite. They have Buffon, one of the best goalies in the world and I would say easily on par with Neuer. Their back line with Chiellini/Barzagli/Bonucci is easily the best in the world and 3/4 of Italy's back, the same team that destroyed Germany in the Euro semis. Juve's middle with Pirlo/Vidal/Marchisio can easily go against what Bayern have. The match up seems exactly like the Germany vs. Italy semi. You have Bayern (Germany), the favorite, going against Juve (Italy), the underdog. I just have a feeling that people aren't giving Juve a fighting chance. Personally as a Barca fan, I would have taken Bayern over Juve if Barca had to play them. No interest in playing organized, tactical, defensive Italian teams.
