The pair have struggled to forge a relationship so far this season, with injuries limiting their time together on the pitch.
However, Bent believes that it is only a matter of time before they strike up a rapport.
"The manager wants to work on the partnership with me and Berba," he told the club's official website. "We haven't really had a chance yet because of injuries.
"On the training pitch we are working on things and trying to get it going. Berba can play with anyone because he's that good a player, but partnerships take time. Hopefully we will be firing on all cylinders soon."
Bent, who is currently on a season-long loan from Aston Villa, has scored three goals in seven games this campaign.
