Manchester United boss Sir Alex Ferguson has backed his former Aberdeen captain Alex McLeish to be a success at Birmingham City.

"I think Alex has proved himself as a successful manager, no matter where he is," said Ferguson. "His contribution to Scotland's success in the last few months has been fantastic - everyone in Scotland is so proud of him, because it's not an easy job.

"He's brought great belief to that team - and following on from what Walter (Smith) did, it's been a great period for Scotland.

"Alex, absolutely no problems, he's a top manager."
