The center back has found playing time difficult to come by in the French capital and says he may have to evaluate his options at the end of the season.
Paris Saint-Germain defender Marquinhos says he may be forced to consider his future at the Parc des Princes if he fails to cement a first-team place.
The Brazil international joined the Ligue 1 champion in July 2013 from Roma, but has failed to become a regular starter, with compatriots David Luiz and Thiago Silva PSG's favoured center-back pairing.
Marquinhos has made just 12 league appearances this term, starting only seven, and Premier League duo Chelsea and Manchester United are reportedly monitoring his situation.
