I agree with the first part of your post. As for the bold part, I think that what we need the most in midfield are talent, and most of all brains/intelligence.
Someone who can control the tempo, distribute balls left, right and forward, create a lot of chances and read the opponents' game and intercept their passes.
Just check this out. All 4 seasons of Pjanic and Pirlo and the last season of our current midfielders. Look at all the red for 2021/22 midfielders (the worst 5 stats are in red, the best 3 in green).

We definitely don't need the current Pjanic, but a Pjanic of the old days would do wonders. Locatelli isn't there yet. Not even close as a matter of fact.
