Not sure about 352 either. Don't know why but I'm watching the Huddersfield game :( and when in possession we are basically playing that formation and it's not working.
The main issue I can see is lees and glen and hutch drop and hunt and pudil push really high up to the half way line and stand their. No movement at all. This basically takes them out of the game as a passing option, and our build up play was none existent.
If we do go 352 Carlos better get his tactic book out and learn how to do it.
