Barcelona have completed the signing of Kevin-Prince Boateng on a six-month loan deal, with the option to make the move permanent at the end of the season.
The 31-year-old has been brought in from Sassuolo to add some extra depth to Ernesto Valverde's squad as they prepare to challenge on three fronts during the second half of the season.
If Boateng impresses between now and June, Barcelona will have the opportunity to sign him on a permanent basis for a fee of €8m.
Boateng returns to the league
He has also spent time in the Bundesliga with Schalke and Eintracht Frankfurt before signing for Sassuolo last summer and scoring in three of his first five Serie A appearances, though he has struggled with injuries lately.
This is the second consecutive transfer window in which Barcelona have done business with Sassuolo, having sold youngster Marlon Santos to the Serie A club last summer.
Barcelona have a vested interested in maintaining this relationship, as they may try to sign Sassuolo midfielder Stefano Sensi in the near future.
