Or just insert any top-half Serie A or Bundesliga manager
You're underestimating the difference of pressure of managing a big club, especially one like United. We can't just insert any flavor of the month manager into one of the biggest clubs in the world. If Ole didn't have a history with us and wasn't recommend by SAF, he wouldn't get anywhere near the job even as bad as we were after Jose.
Out of the ones you've listed realistically only Zidane and Conte would be suitable. Brandan Rodgers is a huge maybe, but his Liverpool past puts a huge doubt over that. Mancini is a definite no.
