Mancini signed Maicon six years ago while he was in charge at the San Siro and, earlier this week, the player's agent said that the Italian was chasing the 31-year-old again this summer.
"I don't know. I bought Maicon when he was at Inter, but now he is an Inter player," said Mancini.
"No [interest], not at the moment."
Maicon has been capped 66 times at senior international level, scoring six goals.
