Butland is focusing on sealing his place in Birmingham's first XI.
"I want to play as many games at the highest level as I possibly can," he told the Daily Express.
"I should be pushing for a first-team place at Birmingham. That's what I want, not to be sitting on the bench. It is time I played now.
"I've had some great experiences with England at the European Championship and I can't wait for the Olympics to start. My name has been linked with some interested clubs and that's flattering. It's not an option for me now though, I need games."
