Bell played all round a full delivery, and a dejected Collingwood, who has scored just 63 runs for club and country this summer, was flat-footed as he nicked to slip.
When Kevin Doyle held off Brede Hangeland on the right there looked to be little real danger, but the Irishman clipped an enticing cross to the back post and Van Damme side-footed the ball back across a scrambling Mark Schwarzer to claim his first goal for the club.
