You're focusing on but one point, when I was trying to point at multiple causes.
- The handballs: one was a clear case that should have been called. So much is true. The thing about video replay is that it will never be accepted beyond goal review. I say never... Of course I could be wrong, eventually, but in what's coming in the next few years, only goal reviews are on the book. So this is still something we'd need to live with. Also: 2 actual goals that are not good is not the same as one or two "could be goals". People miss their penalties. I'm not saying it's likely, I'm saying it happens. That's all I need to show that the two cases are not the same.
- Barça has a number of players on their regular team who play at the international level. They are not a "one man army". Having Puyol and Mascherano out is what really hurts. Choosing to play Messi instead of Villa or Fabregas, that's also questionable if you know he's not going to help the team. Which leads me to...
- The team has not rallied behind Tito. I see many clues to that effect. I might be wrong, of course, but it looks as though they lack the discipline that a team would have facing Bayern, the kind of discipline that stems from direction provided by the coach. Losing Pep, then losing Tito in Jan., has really shaken them.
- Yet for all that they'll still win La Liga, which is one of the toughest leagues in the world.
Expect a trade this summer... and for someone taller and more talented than Song.
