I think if Ange is to make it work long term a few things have to happen.
1 new coaches. He needs to bring in coaches who coach off the ball movement, pressing and defending. Playing a high line doesn't make you concede more goals but if your press isn’t right you can be got at easily. Last season our press was a mess. Fergie used to bring in assistant managers who were good at different things just to evolve his team, take a page out of that. Without this we will always be Liverpool’s bitch.
2 Club backing. Proper backing, I mean Cherki, Eze, Corsoda, new Striker, LCB and maybe an elite midfielder of both Bentancur and Bissouma are off. To play as bold as Ange plays you need more elite players.
If the above two don’t happen I can see a mid season sacking as the league form was horrific.
