McLeish brought in Nikola Zigic from Valencia during the summer and the Serbia international is only just coming to terms with the demands of the top flight in this country.
But he is aware any signing during the next month has to be ready-made to join the fight to stay up ahead of the clash at Blackpool. Robbie Keane, Jay Bothroyd and - on loan - Ryan Babel have been linked with a move to St Andrew's.
McLeish said: "We are working actively, the board and myself, to try and enhance the striking positions.
"The board are understanding of the situation and there are a few names we have talked about that could enhance the team. They are trying to help me to bring those players in.
"You are not going to bring in players lesser than the ones you've got. You are trying to bring in a bit of quality to make sure it can improve the team. We've got to be bringing someone in who can go straight into the team. That is the type of player we are looking for."
