Re: Transfer spend - Ole spent same as Mou (in Net he spent lesser than Mou). Ole spent lesser than LVG as well when looking at spend/summer values.
Re: Atmosphere - The atmosphere under LVG improved slightly only because it became clear he was getting sacked at the end of the season, and the atmosphere under Mou was way worse. It improved after his sacking only because we brought in Ole
Re: Youngsters - It's not his fault that Greenwood turned out to be a cnut. And McT became an integral member of the team under Ole, unlike his predecessor, where he was played sometimes as CB to make a statement to the board
Re: CL places - Literally everyone missed CL places when they were sacked. This time around, Ole was sacked when we were 6 points from top 4 with 26 games to go. 3 points from 4th best top 6 club then, so it's not as if it was out of reach. When Mou was fired, we were 11 points from top 4 FYI. And Jose didnt finish in top 4 in 2 consecutive seasons by the way.
Ole spent more than Jose with nothing to show for except the top-4 cup. Ole spent a lot more than LvG, again with nothing to show for.
The atmosphere under Ole was shit as well. There was a lot of booing at our ground until he was sacked. And he overstayed his welcome by being a legend as a player, if anyone else would be in his place he wouldn't last until December 2019.
Fair enough on Greenwood, but you are forgetting that Jose wanted to promote him at 15 and McT got his debut with Jose and was considered a valuable member of the squad. He only played him CB in his final season, as you say to make a statement.
Sure when Mou was fired we were 11 points of the top 4, but everyone lost points and we bottled countless opportunities to get there. Basically if I remember correctly it was between us, Arsenal and Chelsea(?) (to bored to look it up).
Jose didn't finish top 4 in consecutive seasons but we did play Champions League 2 consecutive seasons. So mission accompliced(?) and with a cup won on the way.
