Villa currently sit third on the table, three points behind leaders Arsenal.
"Morgan Rogers is something special," Carragher said on Sky Sports. "He's been one of those players that has sort of come from nowhere.
"They signed him from Middlesbrough for not a huge fee and he's gone on right now to not just being one of the best young players in the Premier League, which is what he was last season, but he's now looking like one of the best players in the Premier League.
"That could be key if Aston Villa do feel that they could go on and contest the league title or go on and win it."
Carragher added, "Can Villa win the title? I don't think they can, but if you are to win a title, and let's say Man City go on to win a title, they have Erling Haaland, who is the best player in the league.
"If I look at Arsenal right now, I think of Declan Rice. If they go on and win the league, I see Rice as a player of the year candidate.
"But with Aston Villa, who could drive them to the title? Who is that special that they could be head and shoulders above everyone in the league?
"The one player I look at is Rogers. PFA Young Player of the Year before, could he now go on and be PFA Player of the Year this season and drag Villa really close to a league title?"
