the 4-2-3-1 worries (which i dont share) were that we didnt need 2 holding mids which are currently McFred.His 4-2-3-1 at Molde wasn't negative at all, but rather very attacking. All formations could be attacking and all formations could also be used to stifle and react to the opposition. It all depends on how the coach wants to approach the game regardless of the formation.
The formation isn't important but rather how the coach wants to implement his style of play. Bayern used a 4-2-3-1 when they won the UCL, but the difference between us and them is that they play that style by implementing a high line in a very imposing manner, on the ball and off the ball.
So when I said earlier about, what's being reported is similar to what I predicted. It didn't have anything to do with formations, but rather us playing a more imposing game by playing a higher defensive line which would help us both on the ball and off the ball due to us having a counter pressing threat aswell as being much more effective at transitioning play.
