Why put out the same formation when the intend is different, why would he start Bale if the intend was to defend when everyone knows Bale is questionable at best on tracking back.You're confusing formation with intent. It was a low block set up, we didn't press high and got ourselves into a malaise of not being able get out which negated our strengths- Bale, kane etc.
And even if you're right which I don't think you are, even if you're correct and the players just didn't perform then you still have to question him as they aren't playing for him.
But we know Mourinho’s often favoured tactic is a low block without the ball. He has never hid it.i suspect he just didn't have the courage to fully back it up and drop Bale and n'dombele or lucas to ensure we had the defensive energy to do it well.
What you’re saying is that Jose is simply hoping for the best when he sent out an attacking team to actually defend. That’s just a laughable view on a manager with his experience.
I would have agreed if you are having a go at him on not successfully motivating the team for a derby but it’s just absurd to suggest the tactics was to stand off arsenal and be as negative as we did with the players he had started.
