There seem to be two camps of people currently when it comes to ETH assessment, you either dismiss his achievements or are willing to give him a free pass on almost anything that happens because he can't possibly do anything better with this current group of players.
I think several developments from this season are highly encouraging. We have been able to dominate lesser teams and win convincingly on a regular basis, which to be fair had not been the case for a while prior to now. Even in Ole's best seasons a lot of those wins felt lucky and relied on moments of brilliance, it's much more consistent now and it's a big improvement. It's also something he was able to translate 1:1 from his time at Ajax as that's basically how 90% of his games over there looked, with only 2-3 teams in Netherlands capable of going toe to toe with them at times. This is very important and lays good foundation for future because by disposing of lesser teams we almost guarantee that we are going to be in top 4 race every time, we will not fall away into obscurity the way Chelsea and Liverpool have this season, and it definitely provides us with a good platform for future. It also ensures that we can go far in cup competitions with some luck in draws - e.g. our League Cup run this year where we faced almost exclusively poor/weakened teams and got through them easily, we basically won a cup without facing a decent team until the final. It's encouraging.
His big game management has been largely poor, in particular away from home. We've made the same exact mistakes setting up against good teams at the beginning of season as we do now and there has been no improvement on that end whatsoever. Our game against Brentford in August was basically exactly the same as our game against Sevilla yesterday, just with different timing of goals, and our game against Liverpool basically mirrored our game against City earlier in the season. We should have lost by 5 to Newcastle as well while we are at it. You can put yesterday down to our defenders not being available but truth is we played exactly the same type of football and made the same mistakes when they were there. I don't really understand how you can be not concerned at all by this, we basically turn into a relegation fodder every single time we are away to a top team, there's no difference between us and Nottingham or Southampton, arguably we at times look even worse than some of the bottom half teams. I also don't buy it is strictly a personnel issue, yes we are lacking quality in many areas of the pitch but it doesn't justify being this horrible at all. The fact that we have made absolutely zero improvement on that end throughout the season, none whatsoever, is concerning because we definitely made a lot of improvements in our performance against weaker teams.
I hope he can learn from his mistakes and iron them out without relying on having the perfect team available at all times. This was one of key Ferguson's strengths, we could have gone out there with virtually any team and would almost never get hammered. We competed against good teams without midfield, we played Gibson and Cleverley for chunks of the game and were almost never ever battered. We always tried to fight back, we would never surrender in the middle of games and let ourselves be embarrassed. We could actually still win titles by being horrible against good teams and being great against weaker teams, as that's how the league works, but it's not sustainable over long run. And we can't always blame this on players not being available, it's going to happen time and time again in the future, we will have injuries, suspensions, we need to learn to deal with that and not throw in the towel each and every time we face adversity.
