Barry plays mainly in a holding midfield role for England, but at Villa he plays in a more attacking role and O'Neill believes this is the best position for the 27-year-old.
Speaking to the Birmingham Post O'Neill said: "He (Barry) wasn't alone, but he was really magnificent. He was back to his best at club level.
"Interestingly, he plays a totally different game (than when playing for England). He's not a holding midfield player for us. If he is, I've picked the wrong player.
"Stiliyan Petrov is the central midfield player and Gareth is given a licence to go and play but he'll get back and do his job as well."
