The young midfielder has been linked with Nottingham Forest. But after featuring in victory at Wolves on Saturday, Lewis says he wants to stay with the Sky Blues.
"I've never ever seen myself at a different club - I've always wanted to play for City," Lewis said.
"It's my dream club, and like you see (at Wolves), when I'm playing with the kind of players that I'm playing with, it brings out the best in me, so I'm so happy."
On his playing status, Lewis also said: "Everyone wants assurance and security, but at the end of the day, it's on me. It's on me to perform. It's on me to take the chances when I do.
"After that, there's nothing I can't blame myself (for). If I take my own chances, I do it. If I don't, then I have to work and get better.
"Last season I played more than the season before, this season I want to play more than last season, so it's always the same goal - becoming an established player."
