Stevens impressed on his full top-flight debut last Saturday, but was critical of himself for switching off for Manchester United's last-gasp winner in the 3-2 defeat.
"I'm hoping to keep my place, I've got confidence," Stevens told the Birmingham Mail.
"I'll go into training and train well and hopefully I'll stay in the team for Manchester City.
"I've trained with the first team every day since I've been here. This debut has been a long time coming, but when you get your chance you've got to take it.
"If we play like we did against Manchester United there's no reason why we can't get a result against Manchester City. It's a great experience, it brings out the best in you. You know where you stand when you play against the best."
