However, Jansen feels its only a matter of time before Graabi regains his goalscoring touch.
"Ciccio's a wee bit low on confidence at the moment, but he's got some good touches on the ball and he just needs a lift," he told the Lancashire Evening Telegraph.
"He's bubbly around the dressing room and he is enjoying it here, but he just needs the lift that maybe a goal would bring.
"He's been working harder this season. It's unfortunate things didn't drop for him on Wednesday night, but on another night they would have and that would have made a huge difference."
