Birmingham manager Alex McLeish admits his side have to start posing more of a threat to opposition defences after drawing a blank at home for the third successive game.
The long unbeaten home record came to an end against Everton after goals from Tim Cahill and a Roger Johnson own goal and McLeish wants more attacking threat.
He said: "I have thrown down the gauntlet to all our strikers. Places are up for grabs in the front areas.
"I want to see more in training and reserve matches and the opportunity is there for someone.
"Cameron Jerome is putting himself about up front but we need someone else to be a threat up there."
