Hopefully mate.
You asked what the turning point was at Celtic: Interestingly he started to turn the corner very soon after where that thread was linked.
He'd gotten off to a really shaky start and although most of the support was giving him time, there was a feeling that if he'd dropped more points in that final game before the International break (away to Aberdeen), the pressure was going to start to seriously build. As it turned out, they scored a very late winner which settled everyone's nerves.
If you read the first 20 or so pages of that thread, it's basically a carbon copy of this one. Loads of people asking who the fuck is this guy, is this some sort of stick joke, etc.
Look, I'm firmly in the pro-Ange camp and have faith in his ability to achieve something special here, but I'm also not blind to the challenge. Although it wasn't easy to overturn a Rangers side who finished the previous season about 25 points ahead, trying to overtake the best teams in the Premier League is a different prospect entirely. His first season was evidence of that.
It's going to take time and transfer windows, that's the reality of it. The backing in the transfer marker is obviously crucial (insert Levy emoji here). There's evidence that when we have players capable of playing his system, we're a really decent side. For example, in the matches where we had all 4 of our first choice defenders last season, we had the 4th best defence in the league (that'll be skewed by quality of opposition and the like, but it still illustrates the huge drop off we saw when Davies, Emerson, etc were forced to play)
Of course he also needs to be showing progress along the way (winning a cup would help immeasurably) But it's important to remember that he's a very process driven manager. The first season invariably is always about instilling principles and a style of play, the growth should come after that.
