Just watching how easy City are breaking up Liverpool's counter attacks. Literally within seconds they shut the door and win the ball back.
Then contrast this to us yesterday and against Villareal. We can't win the ball back or do the dirty stuff on the halfway line. This is the area where the battle is won and lost. Boss this area and you control the game. Even if one City player is bypassed, 2 or 3 more are backing him up. We could learn a lot from these attributes.
Incidentally, imagine if they had Ronaldo up front. They'd be 3 up at half-time.
