Swiss league leaders FC Zurich have signed Tunisia striker Francileudo dos Santos.
The 27-year-old moves on loan from French club Toulouse until the end of the season.
"Santos is exactly what we have been looking for, he has international experience and will be able to help us out," said FC Zurich coach Lucien Favre.
Zurich, who are seeking a Champions League place, will make the deal permanent if the Brazil-born impresses during his six-month stint.
Santos scored 53 goals in 144 league matches for Sochaux before joining Toulouse.
But he has failed to reproduce the same level of form since leaving Sochaux in 2005.
