Chelsea are on red alert after Ajax coach Erik ten Hag confirmed that star players Donny van de Beek, Andre Onana and Nicolas Tagliafico could all leave this summer.

According to Ten Hag, Van de Beek and Onana will be allowed to leave Ajax this summer if the offer is right.

27 year old left Tagliafico, who has been linked with a summer move to Chelsea, is the most likely to leave Ajax this summer due to his age.

“The transfer market will start in August – the top leagues are now being played out, so the money flows are maintained,” Ten Hag told Dutch outlet Het Parool.

“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 remains to be seen 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.”
