Marquinhos says he is happy at AS Roma.

The defender continues to be linked with Manchester City and Barcelona.

"I'm thinking about respecting my Roma contract, one which ties me to the club for the next four years," the former Corinthians player told Globo Esporte.

"If an offer arrived then my agent would look into it, but I'm just focused on playing football to the best of my ability.

"The rumours are nice, but I'm not thinking about them. I'm remaining calm and focusing on doing well for Roma."
