The thing was, the straight red was harsh but a booking would have been expected and that would have seen him sent off anyway. Terrible piece of playacting from Busquets though, really poor.
Barca have been far too one-dimensional so far, although that's mainly because Inter are just sitting so deep and letting them do what they want until they get towards their area. Alves seems to be the best source of space for Barca, and Pedro has found some space out on the left as well - the trouble is that Samuel and Lucio are so dominant in the air that Barca's crosses would have to be perfect.
It's been pretty much as I'd have expected to be honest, I found that a decent half really. Would obviously have been better if the game had flowed more, but Barca's gamesmanship and Inter's time wasting is preventing that.
