Manchester United striker Mame Biram Diouf has been granted a work permit and will be available for selection in January.
Diouf, 22, joined from Molde in the summer but has remained at the Norwegian club on loan while the permit issues were resolved.
Diouf, who has one senior cap with Senegal, has been impressive in training and could now be given the chance to impress in the United first-team in the second half of the campaign.
Sir Alex Ferguson said: "He's been training with us and is looking very exciting. That's the kind of situation we're good at - finding young players who can develop at the club and, at 22 years of age, he's looking very good."
