Many ?modern? managers are very stubborn and refuse to change their system.

And, too many of them, want to play ?the Guardiola way? but alas lack ?the Guardiola players?.

And they are so keen on being ?modern? that they rather stick to a ?modern? system which is failing, then change it. It?s like it nowadays is embarrassing to, sometimes at least, be direct and, heaven forbid, go 4-4-2. Then you?d be labelled as an archaic dinosaur.
