His tactical nouse ends when the opposition changes shape and start pressing us. Agree that Coleman is dire at the moment, Miralles is a liability. but FFS you're 2-0 up with 10 men - You do not put another striker on! And I use the term striker loosely. You stop them getting at our full backs and whipping crosses in. You defend and fight like lions - you get dirty. What you don't do is think your Brazil and go all out for another goal.
