Ajax sporting director Marc Overmars has stressed that the club have no intention of cashing in on key assets Kasper Dolberg and Amin Younes during the summer transfer window.
Both players have reportedly attracted interest from sides on the continent, having caught the eye during the Dutch giants' run to the Europa League final last season.
Dolberg is said to be on the radar of Manchester City and Manchester United, while six separate clubs have been tipped to make a move for Germany international Younes.
Neither player will be sold by Ajax before the August 31 deadline, though, having already lost Davy Klaassen to Everton and Bertrand Traore to Lyon following the expiration of his loan deal.
"Kasper Dolberg and Amin Younes are not for sale," Overmars told De Telegraaf, while also adding that centre-back Davinson Sanchez has a £35m price tag.
Ajax recently named former reserve-team boss Marcel Keizer as their new manager following the loss of Peter Bosz to Borussia Dortmund.
