I think this season needs to be viewed in the context
Last Summer I felt Solskjaer should walk away from the job before a ball was kicked. He was going into the season with a really under-equipped squad and was under real pressure from the word go. I felt the Glazers/Woodward were taking advantage of the fans emotional attachment to Ole and throwing him under the bus when we got rid of so many players and went into a season with Rashford, Martial, James, 17 year old Greenwood as our attacking options - Pogba wanted to leave and our Number 10 options were Lingard/Pereira. And, as expected we were piss poor and inconsistent for months on end. I'm pretty sure we had a record breaking bad start to the season in terms of points didn't we.
Fernandes joined at the tail end of January and our football has improved drastically. We've seen real positivity around the team and the mood is completely changed. I think that signing gave us hope. To make up 18 points on a functionally very good Leicester side is a real achievement given how poor and disjointed we were in the first half of this season and under Jose beforehand. Getting top 4 has been a really important experience for our young squad who've had to play through the fatigue barrier, under the pressure of having to win every game. A great experience for a young United team who've been the best in the country post-lockdown.
We're now at a pivotal point where good smart investment could have us cement our top 4 position and move towards challenging Liverpool who, in truth are miles ahead of us. Their front 3 are at the tail end of their 20s and they've been very fortunate with injuries yet again. My aim next year would be to get much closer to them - not sure we are ready to properly challenge though. It really depends on transfers and on how this Liverpool side can maintain consistency and keep key players fit.
I didn't celebrate top 4 like a trophy but it is far more important than a league cup or FA cup in terms of getting back to competing. Under Glazernomics our budget is tightly allocated - CL will have us shopping for the best players rather than picking scraps or players more motivated by money than playing at the top level.
I'm delighted today but I wouldn't say I've seen anyone properly 'celebrating'. To get so triggered over United fans enjoying the achievement - and in context it is a real achievement - I'd say the OP is the one with the issue
