I am not saying that Amorim is going to turn it around but he needs at least a pre season and some better players, if it doesn't work by November or at least show some form of progress then the discussion on changing could start.
Fergie is and will always be the greatest manager of all time but his first squad did contain:
Gordon Strachan
Paul McGrath
Bryan Robson
Norman Whiteside
Frank Stapleton
These are far better player than we have now, take nothing away from what Fergie achieved, but how many of our players are on the level of some of these?
This is the worst squad we have had in certainly the PL area, cannot comment past then, with the injury to Amad, Garnacho is our best attacker, every time he gets in front of goal it's more like a rugby conversion than a shot.
The truth is we are so far off it, no one is waving a magic wand and turning us around, it is going to be sh1t before it gets better, at least let the man who has seen these players for what they truly are and won't be fooled by the time pre season comes around shift some on.
If he doesn't work at least he will have started the work for the next manager.
That's kind of beside the point for two reasons, first the point was about SAF improving things immediately which he did unlike what many are claiming, he took over a team that was deep into a relegation battle. The second point is that while it's true that the current team is maybe the worst that we have in the PL era it's not actually a point to make because the expectation isn't to win the league with relative ease and go far in the CL, the expectation is to be a respectable EL spot contender or at least midtable team.
As for your last point would you say the same thing about ETH at the start of October 2024?
