Paris Saint-Germain have confirmed that Rafinha has joined Real Sociedad on loan until the end of the 2021-22 season.
The Brazilian midfielder has struggled to get a look-in under Mauricio Pochettino at the Parc des Princes this term, making just five appearances in Ligue 1.
Not since October 15 has Rafinha played a minute of league football for PSG, leading to talk of a move elsewhere during the winter transfer window.
Now, Les Parisiens have confirmed that the former Barcelona man has returned to La Liga with Sociedad, where he will spend the next six months.
The deal is not thought to include an option or obligation to buy, with Rafinha still contracted to PSG until the summer of 2023.
The 28-year-old has registered seven assists in 39 games in all competitions for PSG and previously made 117 appearances in La Liga for Barcelona and Celta Vigo.
