Alex McLeish has drawn a line under his attempts to sign Spurs midfielder Kevin Prince-Boateng on loan.
The Blues boss has been pursuing the German under-21 international for several weeks in an attempt to bolster his midfield.
But despite the two clubs coming to an agreement, McLeish has been unable to meet Boateng face to face and has now decided to pursue other targets.
"He's (Boateng) disappeared off the radar," said McLeish.
"He's still in Germany as far as we understand.
"We haven't heard anything else from Spurs, Boateng or his agent.
"We've got to move on because we can't wait for ever.
"But until I hear something we're going to pursue the guys were looking at the moment."
