I'm not asking you to believe me that he did nor to agree with booing a player. I'm asking you to recognise the fact that the accusation was levelled against him during, and in the immediate aftermath of the game – both before Castle's article came out. You can think that the accusation is misplaced, as perhaps did the majority of people who did not boo, but it doesn't change anything. Once that is recognised then all it becomes about is a simple point: people feel strongly about players they feel have let down the team because of a lack of effort. Whether that pales in comparison to what Mourinho has or hasn't done is somewhat besides the point. If anything, I guess it just shows you how strained the relationship between Pogba and match day fans has become if he can't even win a popularity contest with a manger that most people will agree with you about.
