Of course he's a great but the fact you need to mock Fergie's time at Aberdeen and don't understand (or dont want to) the magnitude of his success there says a lot.
This is it, I guess there are a lot of people born after his success at Aberdeen, they cannot fathom quite how gargantuan an achievement what he did there is still to this very day.
Pep can win as many league titles as he wants, spending countless billions or trillions there doing so, and he will still not get close to the achievements that Sir Alex did with Aberdeen.
He has had it easy in his time as a manager in comparison to Sir Alex, he was gifted the Barcelona job, yes they were underperformed by their standards, but it was still the Barcelona job, it wasn't Cadiz, he didn't take Cadiz to European glory, or a small team like that did he?
That is why until he does, he will forever be behind Sir Alex, and what Sir Alex has done.
Same for him being behind Jose, as Jose took Porto from just a Portuguese club, into a European powerhouse, doing what to my knowledge, no one else has done, winning the UEFA Cup, then the following season winning the Champions League, that initial is an extraordinary feat in itself with a money bags club, but Porto, wow, then when Jose was at Chelsea, he had a season where they conceded something unbelievable like 10 league goals all season, on the way to the title, again that was unbelievable.
For me Pep is behind Jose, nevermind being light years behind what Sir Alex has achieved in total.
Pep has been very successful no doubt, but he hasn't truly been tested, as he has always been at the richest club, where he can just buy his way out of things, if there are any issues.
Grealish alone was probably 100 times, if not more what Sir Alex spent in total at Aberdeen.
People should be far more respectful of what Sir Alex achieved with Aberdeen, especially beating Real Madrid, that was just simply an unbelievable feat, probably something we will not see ever again.
Leicester winning the Premier League is the only thing that could even remotely come close.
