Charlton Athletic's new head coach Bob Peeters is hoping to convince out-of-contract pair Michael Morrison and Diego Poyet to sign new deals with the club.
Former Belgium international Peeters, who replaced Jose Riga at the end of last month, said both defender Morrison and midfielder Poyet were key to his plans.
Morrison, 26, was a virtual ever-present for the Addicks last season.
"We'd like him to stay," Peeters said at his first press conference since taking charge at The Valley.
"He's a free player at this moment but we've made him an offer and are on speaking terms. I know he played 50 games last season so we'd like him to stay.
"But it's up to the player. We can only make him an offer and hopefully he will make the right decision."
Academy product Poyet, son of former Chelsea and Uruguay midfielder Gus, made his senior debut in January and was voted the club's player of the year.
"He is another player we are still talking with," added Peeters. "He's a very talented player and he showed that against a lot of teams last season.
"Again, we'd like him to stay but it's up to him. We've made him an offer and we've stayed in contact since, so we hope he makes a good decision and stays with Charlton.
"We cannot do more than we've done. We try to contact him every day but we don't want to push him. We hope he'll be there for training on Thursday."
Midfielder Yoni Buyens became Peeters first summer signing when he arrived on loan from Standard Liege on Saturday and more new arrivals can be expected.
"We still have people in the pipeline so it's looking good so far," Peeters said.
