That player must've done or said something to trigger that response. No way that comes out of nowhere. (I'm not excusing anything).
Game was a bore fest. I realise it's preseason but the friendlies are becoming quite the farce. Almost 50 players used between the teams. Refs don't actually want to do any reffing. Opposition has a competitive game in two days. How much more constructive would a United probables vs possibles match be?
Also, note four at the back ;)
