Bannan admits he's relishing a return to Bodymoor Heath next month for pre-season training under the tutelage of Lambert.
He told Villa's website: "There's a real positive vibe about the club and that's great to feel.
"I was obviously meeting and greeting fans at the kit launch festival and you could really feel the positivity of everyone associated with Villa. That comes from having the new manager join.
"It's echoed by the players too. We're excited and we have a real buzz now as we approach the return to Bodymoor for pre-season.
"We all can't wait to get back and show the gaffer what we're all about. We are really excited. It's a new start for everyone."
