PSG midfielder Rafinha is in line to return to the LaLiga in January.
Rafinha is being made available by PSG for next month and a move to Real Sociedad is being setup, says Mundo Deportivo.
A full agreement has not yet been reached, but on each side, optimism has been expressed for a positive outcome.
Rafinha wants to leave Paris in search of regular football as he seeks a place in Brazil's World Cup squad for next year.
For their part, PSG are willing to send Rafinha away on-loan for the second-half of the season.
