PSG's young Brazilian may be open to continuing his career elsewhere after just one season in France.
Despite cantering to the Ligue 1 title, French giants Paris Saint-Germain have already indicated a willingness to make top class additions to their squad over the summer.
Unperturbed by UEFA's FFP restrictions, the Parisian outfit have already agreed to sign their FIFTH Brazilian international defender, shelling out a huge £40 million for Chelsea's David Luiz.
PSG clearly like the look of the Samba centre back, having paid huge fees for Brazil captain Thiago Silva and youngster Marquinhos, as well as the slightly more modest recruitment of Alex, another former Blues defender, and left back Maxwell.
It has led former Roma prodigy Marquinhos to question his future in Paris, something that has alerted former suitors Manchester United and Barcelona. Both clubs are looking for defensive additions after losing Rio Ferdinand and Nemanja Vidic, and Carlos Puyol respectively for next season.
The 20-year-old made just 21 league appearances for the champions, and is likely to see his playing time even further reduced by Luiz's arrival.
Speaking at the Toulon tournament, where Brazil are seeking to defend their trophy, Marquinhos appeared open to a move away from PSG, but was not prepared to address it until after the Under-20 competition had concluded.
The defender told Brazilian website Globo Esporte: "I always want to evolve and grow but I need to talk to my agent and PSG about my future.
"I'm pleased Barca think of me. It proves I'm doing my job on the pitch.
"When I've finished this tournament I'll speak with my agent and PSG and we will decide on my future."
Brazil tackle hosts France in the final tomorrow, and it wouldn't be a surprise if Marquinhos' phone starts ringing as soon as the final whistle goes.
