He's a big reason why this squad is seen in that light though. You can't just say that this squad is great and ignore his role in said squad's development, or that Ole doesn't deserve to have a job or manage a group of players like this, when he's a big part of why they are seen in this light.
Cast your mind back when Ole let go of Lukaku, Sanchez, and Smalling et al (and was forced to let go of Herrera) without getting replacements in for at least half of them. The risk that he took in putting his faith in to some of the players I mention below was massive, and the fact that it paid off is something Ole and the players have never really got their due credit for.
Fred and McTominay were seen as jokes, Martial and Rashford were talented but far from being guaranteed sure things, Shaw was a write off. He brought in Maguire and AWB to improve the defence which was midtable quality the season before, and above all else, he brought Bruno in to the team. He brought through Greenwood and Williams from the academy, and will continue to bring through the best possible kids in to the team - not just paying lip service to it like Jose did before him, or like Lampard did the moment he was able to spend some money.
Just look at the improvements made by some of those I listed. Martial and Rashford almost doubled their previous best goals returns that season. Greenwood equalled Best, Rooney and Kidd as a teenage Utd striker in his first season. Fred went from a joke figure, to actually being one of our most important players (a far cry from when I made a thread proposing exactly that at the start of last season and being lambasted for it). These things don't happen in a vacuum, and Ole has played a big role in them happening.
Now, I'm more than open to the idea that Ole in the long-term might very well not be up to it and might not be the man who wins us #21 or #4, but for me, I want him to at least be given a chance to succeed or fail on that metric (as long as he attains the base level of a top 4 finish). That means bringing in the players he wants on time, rather than either a) getting them 6/12 months late and almost fecking up our season in the process (Bruno, the long hoped for Lukaku replacement), or b) not bringing any of them in at all (Grealish, Sancho et al). Unfortunately, that hasn't been the case during Ole's time at the club (while Jose and LvG were able to squander the vast sums they were given).
Give him a full squad (i.e. bring in a starting calibre RW, DM, CB, and ST) and see where we land is all I ask. If we're still in a dog fight for top 4 after those incomings, then we will have to accept that it hasn't worked out and wish him all the best, but right now, I do think he did a fantastic job last season, and decent job this season, all things considered. And irrespective of what happens next, the next man in (if Ole doesn't work out) will have a far, far better and coherent playing squad to deploy than what the previous managers had been left with, Ole included.
