FOUR horrible defeats (Milan, Madrid, Bayern x2), couple of great wins (3-2 against Madrid, 4-0 against Milan), a few draws (in most of which we weren't really the better team, especially the 2 games against PSG, their 2 goals in the first leg were lucky, but they created a lot of chances), and a bad defeat that should have been horrible (2-1 loss to Madrid in the Super Cup)
We were pretty shitty in big games.
Milan was not a horrible defeat. They got beaten 0-2, that's an average football result. A bad defeat but not horrible.
The 0-4 defeat by Bayern, that is what is horrible. For sure.
The 1-3 defeat by Real Madrid was also horrible, since like I said they were 0-3 down and Madrid at that point eased off.
The second leg against Bayern was not a big game since they were already four goals down and knew they were out. Messi and Busi didn't start, then Xavi and Iniesta got subbed off at 0-1. With Bartra in defense too. It's completely unreasonable to use that game as any kind of measure.
In the draws against RM we were the better team. Against PSG in the first leg they had two lucky goals and little chances. They did better in the second leg, but they were chasing the game and Barca were complacent. Once Messi came on Barca were superior right till the end of the game.
Super cup is a friendly and so I didn't count them as big games. But if you do, then Barca were 3-1 in the first leg before Valdes gifted Madrid a second goal. Barca also played most of the second leg with 10 men and were very close to equalising.
Like I said, there's a couple of great victories, a couple of horrible defeats, one bad defeat and a bunch of draws.
