Pep did, Klopp did, Fergie did.
I think what a club/manager needs to do in a rebuilding phase is show improvement each season, show fans there is an end game. With Jose we didn't really see it, we saw a manager trying to win here and now with not too much preparation for continued success. We can see Ole is trying to implement a certain style with a certain type of player, we don't have the players or squad depth yet. In City and Liverpool we have 2 of the top teams in world football, not just PL. Our rebuild will take time, I don't think we are as far off as some think we are. We've went most of the season missing our only creative mid, and a large part missing our centre forward and now missing our top goalscorer.
Let me rephrase. A top manager doesn't need time get results of some sort. You're right, an element of time is needed. But at the same time, they have to make do with what they have and get the best out of it. He's spent £200 million so far. He's had some decent players in the squad when Jose left.
On paper, we are better than Leicester & Sheffield United, yet we trail them in the league. Brendan Rodgers joined in February 2019 (2 months after Ole). Leicester were in a worse position than us. He hasn't had £200 million to spend on players.
This whole give him time rebuild is utter nonsense. He already had a decent set of players, sold a couple, bought £200 million worth of talent. We are still 8th. Now if were 8th and there were clear signs that there something cooking (could be playing style /players improving), I wouldn't mind. We are 8th and playing bad football.
Does all this mean that Ole is making us underachieve and Brendan is making his Leicester team underachieve? I don't know. But I would rather have manager that gets the most of what they have while they build. Yes, Klopp got time, but he made massive strides in his second season. Liverpool have never finished under 75 points in a full season with Klopp. We would be lucky to get 54 this year.
This giving Ole time will set us back years. He's winging it with his smile and should be nowhere near the top job at any top club.
As the previous poster said, Poch is good at making sides overachieve. Imagine making this group of players overachieve? Would we be in the top 4? I 100% think so.
