Dion Dublin admits he worries for new Aston Villa manager Alex McLeish.
Former Villa striker Dublin reckons McLeish will become a hate figure for fans of both sides and a target for abuse wherever he goes.
Dublin experienced the rivalry between the two clubs during his six years at Villa Park between 1998 and 2004. And he says Villa must get off to a flier to take the heat off their new boss.
He told the Daily Star: "There are managers that have gone into jobs under pressure.
"But when you look at the pressure Alex McLeish will be under, it's going to be so much worse - so he has to begin well.
"It won't be just on the match day when he is in the ground. It will be outside the ground as well, when he is going to his car, to his house or out shopping. He is going to get some real abuse.
"In Birmingham there are two sets of fans - Villa fans and Blues fans. And at the moment, none of them like him.
"The football club and the manager have been incredibly brave to go down this route.
"But if there is a manager who has got the skills and who is brave enough and strong enough to take this on, then it's Alex McLeish."
