Gaffers View: Everton Home (0-2)
It was the third home game on the bounce that Blues have failed to find the net and now he wants his side to pose a threat to opposition defenses.
Blues` long unbeaten home record came to an end against Everton after goals from Tim Cahill and a Roger Johnson own goal.
McLeish 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.'
