I don't understand where you get that idea from.Are you seriously comparing what happened to us in the 80's and 90's (4 relegations and a single final appearance over two decades) with United since Ferguson (2 FA Cups, 2 League Cups, 1 Europa League) or Liverpool pre-Klopp (I assume you mean since the league title so 4 FA Cups, 6 League Cups, 1 Champions League, 1 UEFA Cup)?
We are now an incredibly well run club but my word we have taken huge liberties with this squad and future planning and however well we have done I think the execs deserve some criticism in this present situation.
