Bannan, 21 next month, has made the big breakthrough under the new regime in the Midlands.
He told the Scottish Sun: "I knew if I just kept going that the break would come for me. It's been brilliant.
"Last year I was on loan at Blackpool and only playing now and again.
"Now I'm playing in the Premiership for Villa and the Scotland gaffer has given me a chance. Every game I play now gives me more confidence.
"The gaffer wants a passing game and he gave me the nod for the first-team after I'd done well in training.
"It's not just me. It's really encouraging to see a lot of young lads coming through.
"I'll have to work my socks off to stay in the Villa team. Hopefully I'll put together another few good displays."
