The 19-year-old Brazilian has been heavily linked with a move away from Stadio Olimpico, after a series of scintillating performances in his debut season in Serie 'A'.
Barca boss Tito Vilanova has been credited with an interest in bringing Marquinhos to Camp Nou, as he looks to strengthen the Catalan club's defensive line ahead of the 2013/14 campaign.
However, the Spanish champions will face serious competition for the player's signature, with domestic rivals Real Madrid also monitoring his situation.
Jose Mourinho is believed to be the man that first made Real Madrid aware of the South American stopper, and it's for that reason why Chelsea are also in contention for Marquinhos's services, with the newly appointed Blues boss keen to add him to his recently inherited Stamford Bridge ranks.
Manchester City are also rumoured to be considering a bid for the Roma star, but the fact they are yet to appoint a replacement manager for Roberto Mancini, means that a switch to the Etihad Stadium at this stage appears the most unlikely.
In fact, the chance of any transfer for Marquinhos whatsoever appears slim, after he reiterated his commitment to the Italian club, hinting that he intends to see out his contract with Roma, despite being flattered by reported interest.
"I want to respect my deal with Roma," he told Globo Esporte. "I still have four years on my contract and I don't think about the market.
"It is normal that offers and rumours come in please me. But I leave it to my agents. I think only to play."
