Ajax boss Martin Jol is said to be appealing to the club's board to extend captain Luis Suarez's current contract.
Jol has made no secret of his admiration for the Uruguayan striker, who scored 22 goals and made 14 assists for the club last term.
And, with other European club's apparently circling the talented forward, he is keen to tie up his services beyond his current three-year deal.
Ajax commercial director Henry van der Aat revealed that Jol had approached the board to discuss player salaries, but failed to mention any specifics.
"I don't want to speak about personal contracts but in general new coaches put their salary structure recommendations forward," Van der Aat told Voetbal International.
"Where it's needed, and where we can do it, the salary of players will be adjusted, in deliberation with the board of directors."
Meanwhile, the club have offered goalkeeper Kenneth Vermeer a renewed five-year contract.
Vermeer, whose contract expires next summer, looks set to be second-choice keeper behind Maarten Stekelenburg this term but is said to be considering a new deal.
"I will eventually accept a role as reserve," he told De Telegraaf. "With reluctance, but that looks normal to me when you are a professional.
"I would love to play, and if that can't be at Ajax then at another club."
Jol said: "In my entire career I never spoke about a first and second-choice keeper.
"Anything can happen during a season. The best one at the moment plays."
