Villa boss O'Neill: McLeish will be good for Birmingham
"If Birmingham get Alex, and people are saying that is the case, they'll be getting a very good manager, a very good manager indeed," said O'Neill on Tuesday.
"I know the Scottish players have been very pleased with him and the Scottish FA will be disappointed to lose him.
"That's two really good managers they've had in recent times in Walter Smith and Alex. If Birmingham get the chance to take Alex, they should do it."
