Ole was talking nonsense?
You can convince yourself that Ole didn't want Ronaldo, but both The Times and The Athletic reported that it was Solskjaer who pushed ahead with the Ronaldo signing. The Times went on to say that Solskjaer ignored the advice of his coaching staff to sign Ronaldo because he felt Ronaldo's goals would make up for his deficiencies off the ball. This is what happens when you allow a manager who doesn't coach the team to sign players, which then puts pressure on the actual training ground coaches like Kieran Mckenna who is then tasked with coaching the team.
I'm also familiar with your postings and I do know you have mentioned that you were a 'staunch' Ole supporter.
Ole can play the company tune after a decision has been made, and Ole has proven time and time again that he will do what is best for the club, fully realizing Ronaldo's marketing potential. Plus, I don't think United would neither hire a manager who would refuse to sign (and work with) Ronaldo nor stop themselves from getting Ronaldo even if the manager had the balls to do it.
I also think Murtough and Woodward (and the chain above them) really did a number on Ole as his squad had a very fragile mentality after losing the Europa final on a Dave mistake, when Dave shouldn't have even come back into the squad, if it weren't for Henderson's COVID. The marquee signing and our golden boy Rashford, who played through injury to a declining but serviceable levels, both would miss penalties to lose the Euros final too.
Murtough and Woodward put United's immediate revenue generating future above the squad's future (both immediate and long term) by signing Ronaldo. It had repercussions across the entire structure.
Ole already had to play with one hand tied behind his back by not being allowed to just bench De Gea who played himself in the starting position. Maguire was an alright captain, obviously flawed both as a player, and as a leader, but the squad were happy with him as captain. Cavani was promised a fair chance at the starting slot against Greenwood and Martial, which he was already winning from the second half of previous season. Rashford was the obvious 'mercurial star' in the squad, enabled to shine by talent like Pogba (although I think Ole would've taken a good sum for him if there was someone available to replace him) and Bruno.
Sancho to take over the creative burden off Pogba, from the sides, as well as provide the left option for a Greenwood on the right, attack.
In comes Ronaldo.
We already couldn't really play from the back or high line because of De Gea but now we also can't play high press because of Ronaldo. So, Ole's long-term tactics are out.
Maguire is challenged as captain and the squad becomes more divided in groups. I'm not saying he shouldn't have been or whatever. But it happens. It disrupts the squad harmony.
Cavani is suddenly a sub, or at best, his supporting cast upfront. Cavani decides to be fully selfish after the club f**ked him and doesn't bother declaring fit.
Greenwood is being himself. Can't blame that on Ronaldo, I actually think Greenwood was emulating him and was improving as a player, at the expense of being too selfish and missing chance after chance (but that reminded me a lot of young Ronaldo and his selfishness and wastefulness).
Martial was already having a confidence crisis after not being able to score in the previous season (my suspicion is that he stopped trusting himself to score after the Europa League games) and , only to be reminded how important consistency is by Cristiano frickin Ronaldo. The master of "I perform every single day and thus deserve to be here". Obviously, Martial broke into a million small pieces.
Rashford also tried to emulate his idol but also accepting his terms to always receive the ball (Greenwood pretended he never got that memo), which totally threw him off his game. He used to be the guy who was expected to provide the spontaneous spark and go on a dribble to score a screamer or something. Now he was supposed to cross to Ronaldo. That didn't work one bit. Not doing it well, not following instructions, lashing out with selfish episodes. He just couldn't play well in a team that had to support Ronaldo.
Most of the team couldn't. Bruno was fine because he was used to it from their Portugal time. Almost everyone else struggled because of this adaptation combo: not high defensive line and no high press.
Ole paid the price first. Then so did Ralf. Hope that Erik will not have to deal with the Ronaldo problem and has Murtough's support to deal with the De Gea problem soon after.
