Birmingham first team coach Peter Grant admits there "are a lot of bridges to be crossed" before any possible deal for the Tottenham striker is completed.
Spurs boss Harry Redknapp has confirmed that a bid of around £7million has been lodged by City for the Republic of Ireland international.
Grant: "It is a million miles short of what was supposedly breaking last night.
"There is no such thing as a medical having been put in place.
"Alex has inquired about Robbie many times, even when I came here in the summer. When you see top quality players not in the side and you want to add quality to your own squad, Robbie definitely comes into that category.
"Alex has inquired about him, that is open knowledge, as he has done so about a lot of players.
"The quality of the player does not come into question but I think there are a lot of bridges to be crossed yet."
