I'll happily admit I'm not a great one for analysing tactics and the technicalities of what is just a game of football to me. But there appeared to be a clear shift in tactics when Edin went off and James Milner came on, that I assume, was more like the 4-5-1 everyone was clamouring for prior to kick off. Did we look any better for the change in tactics? Personally I thought we looked less dangerous than when we were an obvious 4-4-2.
What I did find concerning is the way we continue to play against teams that play like Liverpool. As plenty of people have mentioned, they get into the opposition, close down quickly, press from the front with all three forwards working really hard and prevent teams building slowly from the back as we like to do. Amazingly, that's exactly how they played against us last season and yet we looked completely surprised by it (again). If one if the players came out and said that prior to the game they'd never discussed how they thought Liverpool would set up and how to combat it, would anyone be surprised, because that's exactly how it looked. By hook or by crook we have to develop a system to deal with teams who play this way because it will quickly become the default method of playing against us.
