Birmingham's McSheffrey: Newcastle boo-boys can do us favour
He said: "We're in the Premier League, they are playing for their future and their manager's future so everything is on the line for them.
"It can work both ways. There are pros and cons. Everyone will expect them to beat us.
"The fans are amazing and they have that plus - but the minus side is if we go a goal up early and silence their crowd I am sure the boo-boys will be back again."
