#1 United have let a fan favourite leave
Very few players in the current United team actually know what it's like to play for the badge. Ander Herrera certainly had no trouble doing so, it was clear that he loved the club. He put in that extra effort on the pitch that showed his desire and the fans loved him for it. Right from his first game for United, he had found a special place among the fans, who adored him.
Off the field too, Herrera has been the perfect Manchester United player. He has always spoken about the club with great affection and has shown in social media too that he is a proper United player. His passion for the club has been evident on the pitch, and while it has let to debates whether passion alone should be criteria to keep a player at a club, Herrera had won fans over with his performance as well as his passion. To let such a player sets a bad example in a time when United are already sweating to rectify their image among fans.
