The Brazilian moves to Molineux for the rest of the season with Wolves retaining the option to make the move permanent.

The deal remains subject to international clearance and Willian Jose obtaining a work permit, and Wolves said on their website they do not expect to have him available for Thursday's (AEDT) clash against Chelsea.

Wolves have bolstered their numbers in attack with their main centre forward Raul Jimenez having suffered a fractured skull against Arsenal at the end of November.

Patrick Cutrone was recalled from a loan spell at Fiorentina and head coach Nuno Espirito Santo now has an additional option.

The 29-year-old Willian Jose, formerly a loanee at Real Madrid, joined Sociedad in 2016 and has scored 62 goals in 170 appearances for the LaLiga side.
