Appearing in Europe's premier club competition for the first time in over 40 years, Villa have won each of their opening three matches, while they are yet to concede a goal.
Their unblemished start continued on Tuesday, with goals from McGinn and Jhon Duran sealing a 2-0 victory over Bologna at Villa Park and moving them top of the league table.
Though Villa are still seeking their first silverware under Emery during his two-year spell, McGinn thinks the Spaniard's place in the club's history is already secured.
"No matter what happens until now and whenever he leaves - we hope it's never - he will certainly go down as one of our club's greatest managers," the skipper said.
"You feed off your leader. He is our leader and we feed off that. No-one can question what he puts in, the effort - and everything which comes his way and our way is on the back of hard work.
"He is just so driven. I have never met anyone like him. He just focuses his full energy all the time.
"He does not let us take our foot off the gas, so we can use all our energy and enthusiasm, and the excitement we have. His determination and intensity is unmatched."
