Manchester United captain Wayne Rooney says England's young players must keep their cool against Scotland.
Rooney marked his entry into England's 100 club with a crucial penalty on Saturday as England came from behind to record a 3-1 win over Slovenia.
"You don't realise until you actually play there what the atmosphere is like," the England captain said of their friendly in Scotland.
"The atmosphere was great when I was in the crowd, unbelievable, but you don't realise until you're on that pitch what it's like so maybe a few of them, you might need to speak to them and say: 'Listen, this is going to be hostile. Make sure you blank it out, relax, and play your normal game. Don't get involved in it."'
