Morley believes Warnock's laid back character and popularity among his fellow pros owes much to his scouse roots.
He told Villa's website: "I am particularly pleased for Stephen because he's from my hometown. I know his father-in-law.
"He went to the same school as me - St Bede's. He knows a few people I know back home.
"I wish him all the best in the tournament. He's really good to have around in my opinion - his character is important. He's a scouser so he's bound to be a good lad. When Villa were successful in my day there were five or six scousers in the side.
"You need the lads in the dressing room who can have a bit of banter and a bit of a laugh domestically and internationally.
"The dressing room can be a lonely place but if you get a good one it is absolutely fantastic.
"I think that's so important."
