The young centre-back arrived at Camp Nou on loan from Fluminense over the summer and has quickly convinced the Catalan club to keep him
Barcelona have excercised their right to purchase Marlon Santos from Fluminense for €6 million, reports Globoesporte.
The centre-back joined the Catalans on loan over the course of the summer, with a purchase clause included in the agreement.
And Barcelona have now moved to secure the future of the 21-year-old who made his debut for the club in November’s 2-0 win over Celtic in the Champions League.
The sum Barcelona have to pay to Fluminense may even be less than the €6m, given the latter are said to have outstanding debts to the Camp Nou outfit.
