Barcelona has offered Dani Alves and €20 million to Paris Saint-Germain for Marquinhos, according to BeIN Sports.
Marquinhos was acquired last summer from Roma, but he appears to likely be the odd man out following the acquisition of David Luiz.
Barcelona have priced Alves at €15 million, making the offer for Marquinhos €35 million.
Barça is looking for a replacement for Carles Puyol.
