Thing I've noticed about RM (this season and last) is that he sets up the team into a formation (like any other manager) but then when the subs start coming on we become a mish mash of players. Sometimes it's not possible to tell where players are playing and in what positions. We got away with that last year but we'll get destroyed this year with such "tactics".
Just watched the goals from the other games. Wow, teams that score goals move the ball quicky and with purpose. Players taking shots and backing off defenders with pace.
Complete opposite of what we do.
