He is a paid employee of BUFC, so should attend training when required.
If every player kept not turning up, the team would be a shambles,AM is right to drop him.
AM is instilling discipline in to this team, much overdue in my opinion.
If these players want to win, they have to know who is boss and toe the line, handwork and discipline brings success, do you think Alex Ferguson would have been successful if he let the players rule the roost.
