Given how early we have GON in his managerial career, who's to say that he doesn't continue to go on an upwards trajectory? He's certainly showing he can improve players, get them buying into what he wants, working heir passes off for him, and has shown a decent level of tactical astuteness as well.
What had Graham Potter done before he went to Brighton? One job with Swansea and bugger all else.
I just think it's very arrogant to assume any other non-elite manager would automatically have more points or be playing a better style of football. You only have to look at how often clubs at our level change managers searching for any kind of identity or success.
How many times have clubs sacked managers in search of some kind of idyllic style of play they think they deserve and then struggle badly? There's plenty of examples in the Prem and Championship of that happening and then seeing their results stall or get worse.
Sometimes people just fit with a certain set of players or at a certain club, just like Nuno did here. I wouldn't be so quick to dismiss what we've got, especially when we haven't even given GON a chance at any significant new signings yet.
Next season he'll definitely still be here, and that will be the litmus test once the squad evolves to more where he wants it.
