"It's 26 years of (experience)," he said. "If I want the players to be clear-headed in that moment, it won't help if I am jumping around and screaming my head off.
"It's not me anyway. It doesn't mean I don't internally feel the anxiety and all those kind of things, but I've learnt that over the course of my career and in those moments, I still may be needed in those moments.
"We scored (against Luton on Saturday) and made a substitution straight away and put Pierre on, if I am running down the touchline just thinking we've scored and won, I'm not helping the team. But that doesn't mean internally I'm not running. It would probably help me if I did it physically as well!
"I think again, my role in that time and it's just me. It's not I think this is the way it should be, it's just me as a person this is the best way I can deal with what is happening. I think my role in that moment is to try and help the players."
