I think the club should (and probably does) have some minimum targets that the team need to meet each season. Unless we go on a big losing streak I don't think replacing a manager mid-season is the way to go. We might crash out of the CL again this year to opposition we "should" be beating. However, I think progressing in the CL is a minimum requirement. We shouldn't be losing to clubs that require a google search to learn who the feck they are.
The team is better. The club is healthier. The culture is more or less back. I like Ole and his approach to players, conferences, all that. He seems like a good man-manager and he knows the club inside and out. That period where watching United was depressing and everything felt coated with Jose's poison is thankfully gone. We are treated to occasionally breathtaking football.
I do continue to question the tactical naivety and even negativity we keep seeing, like against YB, like last season's CL campaign, etc. We knew any manager was going to be hamstrung by the support of the Glazers, or the lack thereof, in securing their targets. I believe Ole has been given enough in new signings to be able to put together a reasonable tilt at the league. I would expect at least quarter finals in all cup competitions, and at least 3rd place finish in the league with what we have. Our midfield is still a glaring hole and I honestly do not believe Fred will ever be lifting the Prem or CL trophy.
The final issue is, who succeeds Ole when his number is up? If he fails to hit those benchmarks (quarter finals in cups, 3rd or better league) I'd say that's a pretty clear indication he's taken us as far as he can. I don't know of any manager who would be able to take the club back to being serial champions while keeping the culture / spirit of the club alive. Our club was sick for a long time, starting with Moyes bringing the wrong mentality. I think the sickness has been cured under Ole. I do question his backroom staff and the tactics they work on because we keep seeming to be one-dimensional and naive. At the end of the season, let's see where we end up.
