Chelsea's move for Didier Drogba is off after Fifa blocked him from leaving Chinese club Shanghai Shenhua on loan before the January transfer window.
The Ivory Coast international, 34, wants to stay fit to prepare for the 2013 Africa Cup of Nations as the Chinese season has finished.
He asked for permission to move, but has been informed that he is not exempt from international transfer rules.
Chelsea had been in talks over a deal for their former striker.
The Blues are short of attacking options with Fernando Torres out of form and Daniel Sturridge injured.
