The forward’s representatives said in a statement on Sunday that they wanted “clarity” over Sterling’s future at the club, since when Maresca has said he had already made his position clear.
BBC Sport understands Crystal Palace are interested in the 29-year-old, while there are reports he has been offered to Aston Villa.
England midfielder Conor Gallagher has left for Atletico Madrid – in an unpopular move with some sections of Chelsea’s support – with fellow home-grown star Armando Broja set to join Ipswich in a loan move with an obligation to buy.
Several other players appear to have uncertain futures, including defenders Chilwell, Axel Disasi and Trevoh Chalobah, and midfielder Carney Chukwuemeka.
“I just communicate the players that I like and the players I don’t like and because there is one week, or 10 days, left of the transfer window, hopefully we can find solutions for all of them,” Maresca said.
“When you find solutions, everyone is happy. When you don’t find a solution, then you can create some problems.”
The transfer window closes on Friday, 30 August.
