I've admitted when I thought he made mistakes. I thought he would go with a 3 man midfield against Liverpool for example.
Personally I don't think we have the team capable of playing a 4231 tactic and think we need to revert to his Newcastle tactic of 541 with wing backs.
Against Palace. I thought we doing OK until we switched to a 4141 and thought that wouldn't end well.
I don't think he's invincible, but at the same time, individual mistakes have cost us quite a lot this season. The main culprit seems to be Coleman, as soon as we can replace him the better. Holgate and Delph are dog [Poor language removed] too.
If we can get in a destroyer to sit in front of our defence, a replacement for Coleman and another winger, it will improve us considerably.
