Reports over the weekend claimed Bent could be sold in January following a dispute with Lambert after he was dropped from the starting line-up and stripped of the captaincy. Bent started the season as skipper before Lambert decided to give the armband to summer signing Ron Vlaar - and the England international was then axed from the starting XI for the games against West Brom and Spurs.
QPR and Liverpool are reported to be monitoring Bent's situation, but Villa insist there is no problem between the striker and Lambert.
"There is not a problem," a Villa spokesman told the Daily Express.
"The manager has explained why he has not selected Darren for the last two games and has said his door is open if the player wants to discuss the matter."
