I get on the flight, all set up and the next thing Ange comes and he’s sitting right next to me.”McGowan was also too scared to disrupt his boss despite needing to visit the toilet, admitting: “I held it in the whole way. No way was I waking him up.“Some of the boys were ordering wine. I was like, ‘just water, thank you’.

He’d have certain rules that were just non-negotiable.“As an average player, I liked that. He just told you what to do and you tried to do it as best you could. He was very good at that.“There are certain managers who are like, ‘go and express yourself’. I can’t express myself at all. Just tell me what to do and I’ll try to do it!”Ange Postecoglou at ForestPostecoglou has started life at the City Ground with a seven-match winless run.It has placed a huge amount of pressure on the Australian, despite only replacing Nuno Espirito Santo in September.Sean Dyche is rumoured to be in the running to replace him if Forest make a change.This follows his sacking by Tottenham in June despite winning the Europa League.
