There has been speculation about Madueke's future, with Arsenal reportedly interested in signing him and claims he has agreed contract terms with the Gunners.
When asked about the situation, Maresca expressed confidence in Madueke's willingness to contribute to the team.
"Personally, I think the same noise was present before the Palmeiras game," Maresca said.
"When we gave Madueke half an hour of playtime, he performed well. Therefore, I have no doubts that if we need him, he will help us," Maresca added.
Maresca also acknowledged that the ongoing speculation surrounding Madueke can be challenging for him to handle, but he hopes the player can cope with the situation.
