Toby Alderweireld hopes Ajax's title win will help persuade their key players to stay at the Amsterdam Arena.
The Godenzonen beat FC Twente on Sunday to clinch the Eredivisie trophy and secure automatic qualification to next season's UEFA Champions League.
Several key members of the Ajax squad have been linked with a move away from Amsterdam in the summer, with star defender Jan Vertonghen among those to have reportedly attracted Premier League interest.
But after losing Luiz Suarez to Liverpool in January, 22-year-old Alderweireld hopes this season's success will be enough to keep the team together.
"With good preparation, we've got a very good chance next season," Alderweireld told NUSport.
"I often said to Vertonghen that he should stay. But if a real club comes for him, where they play good football, it will be difficult.
"But Jan will never opt for the money. He prefers to remain at Ajax, I'm sure."
Alderweireld was delighted to lift the trophy with Ajax, admitting losing to Twente was not an option.
"The whole town, every Ajax fan yearned for the title," he added.
"There was no other option than to win. That feeling also lived in us."
