Oh, I know what Ole can achieve. I've seen it for over a year to make a very good judgement. 6th place last season and this season we are in 5th. If he gets lucky, he could make 4th. But it shouldn't require a best case scenario to get 4th place. That should be a worst case scenario.
When Klopp arrived, he pushed his team from mid table to 2 finals. With Ole...
...this is like trying to debate with someone who says water is dry. It's hard to know if they are serious or just joking.
Continuing with Ole is a risky move. I actually see potential in Ole, he has gotten the tactics right in the big games, he has a squad that trusts him, and he has an eye for talent (arguably all of our signings so far has been spot on) and he seem to know how to handle upcoming academy players.
On the other hand his lack of experience is very evident; his tactics against "smaller" teams are ineffective, in game management is either hit or miss, and how he handles injuries is concerning. Going into the season with a squad this thin was also a rookie mistake.
But like anyone anywhere, you don't always fulfill your potential and the same goes for Ole. He is a relatively young manager and he is learning as he goes which is not ideal for a club with ambition to compete for every trophy.
Us hiring Ole is not comparable to Liverpool appointing Klopp. Klopp had just been a manager at Dortmund for several years, and gotten time to build his squad and get his ideas in place. It would be a better comparison if Liverpool had hired Klopp directly from Mainz, when he was still figuring out his management style and had no experience at the top level. Klopp would probably not have gotten his Liverpool team to two finals if that was the case.
Ok - we can all agree that City and Liverpool were always going to do better than us
