Australia forward Harry Kewell opened the scoring in the 32nd minute, then Congo striker Shabani Nonda netted three minutes before halftime and then two minutes after, both times set up by Abdulkader Keita.
Villa keeper Thomas Sorensen made a fabulous save to block Shabani Nonda's header deep into injury time before Rovers were denied a penalty appeal for handball and then Bentley rattled the crossbar with a curling effort.
