The Blues boss has made no secret of his desire to add a central defender and possibly another striker to his squad before the window close's at the end of this month.
Refusing to be drawn on naming names, the Blues boss told Sky Sports News: "There's a lot of names, maybe 10 or 15, that we've been linked with.
"I think it's suffice to say that we're continuing to look until the window is finally closed to see if we can enhance the team.
"We feel we've got a good quota of midfielders but we certainly feel that we could strengthen in another couple of positions."
