Bruno Zuculini has joined Valencia on loan until the end of the season.
The Argentine midfielder joined the Premier League champions in a £3m deal from Racing Club this month and featured six times for Manuel Pellegrini's side on their pre-season tour. Zuculini was expected to join Sunderland on a temporary deal this summer, but Financial Fair Play regulations prevented the move from materialising.
The 21-year-old has eight caps for Argentina's u20 squad.
