The 26-year-old was quizzed on who has the best banter at Liverpool in an Instagram Live Q&A session on Wednesday.
"I'm going to have to give it to Robbo, just because he's the loudest and he's non-stop. It's, like, non-stop – Duracell bunny every day," Oxlade-Chamberlain said.
"All he does is just cause carnage and just banter everyone, so, yeah, Robbo."
Quizzed on whether his favourite team-mate is to grab a pint with, the Ox continued: "To be honest we never really get a chance to go out much during the busy season and a lot of schedules. We don't really do that.
"But on the few occasions we have as a team, Robbo is definitely good value on a night out. He's a top lad."
