Birmingham City are wary of a Robbie Keane-inspired West Ham United today.
Keane scored on debut for the Hammers in midweek.
Blues first team coach Peter Grant - number two to Alan Pardew when West Ham manager - said: "I worked with Robbie at Celtic last season and it was a privilege to do that.
"He would have been a top, top quality player for Birmingham City. But that's moved on now.
"There is no doubt about his talent and we know we know we've got to be on our game when you've got players like Robbie Keane.
"But we have got good players also that hopefully West Ham have got to be worried about."
