This is silly, social media isn't his job it also represents his life (out side of football), laughing and joking is allowed outside of your working hours!
TBH I am really getting annoyed with the way things are going in football. Players have lives, its not like he is at night clubs, getting drunk, smoking, or stealing taxis.
Most of the time he is with his family, having fun, looking after his mum, and enjoying life with his teammates and brothers.
Lets criticise him for his performances on the pitch and also if he isn't putting in the effort in training or is not keeping fit. I notice during the summer when he was putting in the training which was on instagram also no one had anything to say
EDIT: Also it just goes to show, we complain about there not being characters anymore in football, but as soon as someone shows some individualism, we complain.
