During the match yes as it can make a difference to the game and the way a player performs, after the match though it serves no purpose all it does is create a rift.
His defence conceded 6 goals, so he's hardly faultless.
What rift? At £140k a week, he should be able to take all kind of abuse from inside or outside the team. He disrespect those who paid his wages, he deserved it.
