"So there’s so much responsibility, and the scrutiny for being a player or the head coach at Man United is major. If you are a player at Crystal Palace or Fulham, you don’t experience it," the 47-year-old told iDiski Times.
"Even at Chelsea, Arsenal, and Man City. [Erling] Haaland is just breaking records for fun. That’s a different breed because of the manager (Pep Guardiola)that he has.
"But I mean if you are at Man United, jeez, just if you score one game, and you don’t score the next game, then people ask questions, and then your ability, your quality, come into question, under the spotlight, because you play at Man United. But at any other club, you get away with it," he added.
"So the pressure for players is huge when you play at Man United. And I think that’s why sometimes you feel that there is a struggle because the expectancy level is so much more when you are at Man United than when you are at anybody else."
