Chelsea are reportedly interested in acquiring Victor Osimhen from Napoli and João Félix from Atlético Madrid.
However, Maresca says: "They are not our players, therefore it would not be correct to talk about players in Napoli or - who is the other - players in Atlético Madrid."
However, Maresca says he hopes for another couple of acquisitions before the transfer window closes.
"At the moment, the club knows exactly how I think about what we need, and hopefully we can sign some players before the window closes."
