Tony Mowbray has warned Aiden McGeady's suitors not to bother even picking up the phone as he urged the club's fans to trust his Celtic revolution.
Reports on Friday claimed Alex McLeish was preparing an £8million bid for the Hoops' star player, who has been on the Birmingham boss' wishlist for some time.
But Mowbray said: "Aiden's a very important player for our club in what we're trying to build here. There's no interest whatsoever in listening to bids. Other clubs would be wasting their energy picking the phone up."
Mowbray sees McGeady as crucial to Celtic's hopes of wresting the Clydesdale Bank Premier League title from Rangers.
"I wouldn't sit here and say one player makes the difference," he said.
"But what Aiden McGeady brings is that x-factor for us really, the ability in the Scottish game - where we do play against teams with a lot of men behind the ball - to eliminate individuals, to go past packed defences, to beat two and three men.
"Our financial situation is we don't need to accept bids for players that we don't want to sell."
