After last season’s triumphant return to the Premier League in which the Bluesnoses finished ninth, they have struggled in their second season languishing just two points away from the drop zone.
McLeish admitted, though, that he will be looking to add to his squad in what is quickly becoming a relegation dogfight.
"I'm hoping to add to the squad, whether it's through loans or permanent transfers, but we're certainly looking to try and add to the squad," he said in the Birmingham Mail.
"They [the board] know that we do need a little bit of help.
"It's going to be hectic late December, January. We've got a load of games and to ask the same players to play week in and week out will be tough.
"I suppose it depends on results, because they don't seem to feel tired when they're getting victories. However, I would think we'll use a fair bit of the squad in that period."
McLeish is acutely aware that he may have to look towards loan moves in January after spending big in the summer.
Birmingham splashed the case on Nikola Zigic and Ben Foster who have taken their time to bed into their style of play.
McLeish has been told that funds could be difficult to come by in January, but the Scot is confident that deals could still be made.
"We are looking at the loan situation, and if push comes to shove then we will see," he added.
