"I want Raheem Sterling but I want all the 30 players that we have, but there is no space for all of them. So for some of them, they have to leave," Maresca said after the 2-0 defeat when asked about the former England striker's absence.
The Italian said Sterling's omission was a "technical" decision.
Sterling's representatives issued a statement shortly before kick-off, saying the player had a good working relationship with Maresca and was committed to delivering for Chelsea.
"Given his inclusion in official club pre-match material this week, our expectation was that Raheem would be involved in this weekend’s fixture in some capacity," the statement said.
"As a camp, we have always had positive dialogue with, and assurance from, Chelsea FC in relation to Raheem’s future at the club, so we look forward to gaining clarity on the situation."
Sterling joined Chelsea from Manchester City in 2022 but his form has blown hot and cold for much of his time at Stamford Bridge and he was not included in England's Euro 2024 squad.
