The Catalans have made the Paris Saint-Germain defender their top defensive target and are willing to pay up to 50 million euros to secure his signature in the summer.
An agent and the brother of Paris Saint-Germain defender Marquinhos met with Barcelona last week as talks over the Brazilian's potential transfer pick up pace.
Barcelona plans to strengthen its defense this summer and Marquinhos is the primary target, with the Catalans willing to pay up to 50 million euros ($56M) to bring him to Camp Nou.
The intermediary Giuliano Bertolucci and Luan Aoas, Marquinhos' brother, met with Barca representatives and set out the 21-year-old's salary demands of €4.
