If anything, we're way too patient as a club. Klopp, in his full seasons, finished fourth, fourth, and now second or first. In his second full season he reached a CL final.
Someone doing all that at United would have got all the time in the world. Mourinho got a fecking contract extension after finishing sixth and having a decent first half of the season. Even Van Gaal was only fired when we failed to make the CL, even though we barely scored a goal at Old Trafford for months.
I'm not sure where the idea that we're impatient comes from. No other supposedly top club tolerates failure and mediocrity as much as Manchester United. We still have Ashley Young playing for us. And Antonio Valencia. "Pure flair" my arse, the one "pure flair" player we have is the one that is constantly under attack by supporters.
