In 19/20 it seemed that Ole was building something interesting with the 3 young forwards plus Bruno+Pogba behind them. I didn't want Conte coming here, destroying their confidence, bottling everything up and playing with no width.
Now, there is no young quick forward line. The football quality is really variable, there's no particular style, and it's not great to watch. The age profile of the squad is perfect for him - at their peak or past their peak (Ronaldo, Cavani, Bruno, Pogba, Varane, Maguire, DDG). Martial is barely a football player anymore, while Greenwood is hopefully too good to suffer under a different approach. Rashford, Sancho, and one of those from the previous list will be the main casualties. OTOH, I'd expect the defence and midfield and the other forwards to get better. So on balance, improvement.
He never stays beyond a couple of years, and that fits up perfectly with Ronaldo and Cavani's contract and the others' peak ages. He's also supposedly very demanding, so I don't see him coming unless he can sign someone in January.
So, probably, yes. Personally I'd wait to see if the team is still in the title race in January, then Ole has earned his place for the season. Though the board will wait as long as top 4 remains possible, so this is pointless.
