Gardner said: "I've worked hard in pre-season - we all have. I've played in a few different positions and I'm willing to play wherever the manager wants me to.
"I've said before that I'd play in goal if he asked me to. I just want to do what I can for Villa and if that means playing at right-back, that's okay with me.
"It doesn't do you any harm to be versatile as a young player, because the manager has more reasons to keep you in the squad if you can do more than one job.
"Gabby Agbonlahor did a job down the right and as a striker last season and look at how many games he played. He might have his preferred position, but he was willing to play wherever he was asked. I'm the same."
