Since we were talking about tactics and managing a squad. Fergie's team tactics, broadly, in that crazy year. It is insane the kind of stuff he pulled off, which we take rather normally now.
There are two things I feel has been missing genuinely from almost all managers post Ferguson - a clear tactical thought through the squad (and building it accordingly) and the ability to improve players through training. I've been very critical of Ole for these exact same reasons previously too - and while I still am not convinced about his tactical nous (and it is criminal they haven't got in a coach in Ole's team who can help with that, if Ole can't himself), atleast there is some work in improving players (which is still not at the top level).
Part of the reason why I still really like Poch. Sure, his trophy record might not be the greatest, but he improved that Spurs squad so massively and made them genuine Top-4 contenders. Improving players that are already at the club is a must - felt that never happened much with LvG/Mourinho, while it is happening in bits and pieces under Ole (I mean, Shaw and wan Bissaka have improved and so has Rashford to an extent). Although, his squad management, atleast, is decent.
An annoying thing about all our hires is that all of our managers post Fergie have completely distinct (and almost opposing styles). Only thing I'm thankful for, is that the current squad (and potential targets, basis rumours) can play in multiple ways if coached (most of them, atleast). So, that atleast can be managed. But even then, Poch is still a completely different style to what we currently are playing if we do end up going for him later on, which will require a bedding in period, to say the least.
