Martinez has learnt absolutely nothing, he won't be manager next season that is for sure.
All he needs to do is buddy up the flanks, fullbacks bombing on with proper Wingers working with them, the rest will take care of itself, width exposes teams, getting the ball out wide pulls the opposition apart to create space in the middle.
It's how we have played our best football under Moyes's last 3 seasons and Martinez's first.
Martinez is never going to go back to that, and for me that means he'll not be here for much longer.
To be fair, that team he has selected today is a genuine change in shape. It's effectively a 4-3-3 if Barkley is given the free role in the number 10 slot.
So at the very least we're seeing some variation from Martinez today.
