Ajax boss Erik ten Hag has acknowledged that three of his key players could be sold during the next transfer window.

Despite the financial implications of the coronavirus pandemic, Chelsea, Manchester United and Real Madrid have all been linked with the likes of Andre Onana, Donny van de Beek and Nicolas Tagliafico.

Although Ten Hag has acknowledged that neither of the trio will be allowed to leave on the cheap, he has admitted that requests have been made to take on new challenges elsewhere.

Speaking to Het Parool, Ten Hag said: "The transfer market will start in August. The top leagues are now being played out, so the money flows are maintained. The market value of players will be slightly depressed, but not much.

"Based on their performance and ambition, a number of our players also want to make the move abroad. Agreements have been made with Andre Onana, Donny van de Beek and Nicolas Tagliafico, but it must be clear whether the market is indeed breaking loose.

"For Onana and Van de Beek, another year of Ajax could certainly be an option, for Tagliafico it is slightly different because of his age."

Ajax have already agreed a deal with Chelsea for Hakim Ziyech to move to Stamford Bridge next week.
