You can't have everything. Having a midfielder drop into the back 3 allows your fbs to push on without leaving acres of space behind them.
It's exactly what Dier did in what was Pochs best team.
I don't want everything - I'm just offering a counterpoint to the discussion. Palinha for me being a top tackler would be better used closer to the action, we give the ball away alot so having him further forward available to mop up turnovers and win back possession higher up the pitch is preferable. If you disagree fine, doesn't matter
