I'm not really defending Ole, it's more the ethos that we need to emulate Chelsea despite Chelsea being full of shortcomings. If we're to emulate any club, I'd rather it be Bayern. I really feel like Chelsea's success papers over many cracks. Bayern genuinely look a team that can with the Champions League most seasons while Chelsea look like a team that put together a decent run before imploding.
After a lack of success maybe United fans might look a bit enviously at Chelsea but City are probably closer to what Fergie was doing and Liverpool were actually able to compete with a 100 point City team until the very end. I still have yet to see Chelsea reach the levels City or Liverpool have.
Bayern look like they can win the champions league every year because Germany is a world football powerhouse and they pay more than other clubs in germany/every player wants to play for them. They wouldn't be nearly as strong if they were in any other league where there was more than one footballing power. Imagine if our best players forced a move to City (free or cheap) every time they became good enough. So I really don't think comparing how we are run to them is fair.
Obviously City (the footballing aspect) is peak how a football club in England should be run, but we don't have that option. We can't put a plan in place 5+ years ahead of time knowing Pep is going to come to us. That's essentially what they did after Mancini, they just planned for Pep's arrival. If there is someone out there and we are doing that, great, I hope we hire that manager soon. But I don't think that's an option. So that leaves us with emulating Chelsea or Liverpool. Liverpool is more ideal in that they built up from barely challenging for top 4 and won a title within a decade, but that's because they went out and got one of the best managers in football and trusted him every step of the way. Slowly strengthening and eventually peaking at a perfect time. That would be cool, but our club is literally trying not to become Liverpool. We don't want to go decades without winning the league. If we are brave and want to try that method, I commend us for that. It's obviously an option.
So that leaves Chelsea. And with our investment in ready-made players in recent years, Maguire, Ronaldo, Varane, Cavani, etc, that seems to be what we're doing. But we're not doing the single most important aspect of their model, and that's hiring a manager that can win. Chelsea take risks on managers. Even Tuchel had tons of issues with PSG and Dortmund's board before leaving/being sacked. Conte obviously falls out with the board everywhere he goes (but I disagree he leaves his squads in bad shape as Chelsea won shortly after and Juventus kept winning) but he won them a title in his first season (right? and won in his first season at Inter as well after them not being good). I feel like we're taking Chelsea's model but just following it badly.
Maybe I'm wrong and I'm babbling. I don't know, I just think Ole is a bad/mediocre manager and that should be obvious to anyone who watches more teams play than just us. I'd love to be proven wrong but it's going on 4 years of no trophies and the performances are getting worse/more inconsistent.
