Speaking after Villa's 1-0 win at Leeds United, Smith was asked about an injured Grealish potentially struggling to break back into his starting XI.
He said: "Yeah, I'm not sure Jack would struggle getting into too many teams, to be honest! Listen, it's nice to win a game without Jack in the team because, as I said, there was a lot made out of us not winning a Premier League game without Jack.
"But, as I said, they were against Liverpool who went top of the league, Leicester who went second and Wolves who went seventh. They weren't give-me games, that's for sure, and Jack would have been the first cheering that win on from home today."
