Chelsea are still aiming to offload some players, with Conor Gallagher expected to complete a move to Atletico, while Romelu Lukaku, Raheem Sterling, Armando Broja and Ben Chilwell could reportedly leave the club as well.
Asked about possible departures, Maresca said: "I just finished the session now and I am already thinking about tomorrow's session. It is the only thing I like to do, I like to control, If you start thinking about 43 players, 'manager [has] no time,' I think it is not worth it. The [sporting directors Paul Winstanley and Laurence Stewart] are there trying to find solutions for these kinds of players. I am not the guy in charge of finding solution for these players otherwise they have to pay me double."
