Killen managed to score twice for the Hoops in their 3-0 friendly win over Brisbane Roar.
“I know Chris Killen can score goals,” he said.
“He’s physically very, very strong and a team player. If he carries on in the same vein as he did today, will he have a future? Yes.
“Everyone has got an opportunity, the strikers ultimately get judged by the goals they score and their general team play and I think Chris is good at all of those things.
“He knows he’s got a fight on his hands to get the minutes on the pitch to be able to do the damage.
“He’s a good lad and a good professional. The best teams have competition for places and Chris Killen will hopefully intensify that competition for our club.”
