Barcelona have announced signing of Yerry Mina from Palmeiras for €11.8million (£10.4m).
Mina, 23, has signed a five-and-a-half-year contract and will be tied to the club until June 30, 2023.
The Colombian centre-back has also had a €100million release clause placed in his contract.
Mina is expected to replace former Liverpool man Javier Mascherano, who has an agreement in place with Chinese club Hebei Fortune.
La Blaugrana are believed to have had an option to sign Mina for just €9milllion in the summer, but they wanted to get the player in early.
Barca and Palmeiras eventually came to an agreement for Barca to pay and extra €2.8million to sign him this month.
Mina, who was under contract in Brazil until 2020, scored five goals in 21 appearances for Palmeiras, who finished second in the Campeonato Brasileiro.
