According to German media, Werder Bremen rejected the first offer made by Ajax for Klassen.
Ajax now set their sights on Clarkson, and they hope to take him back to his old club before the summer transfer window closes.
However, reports claim that Ajax’s offer of 7 million euros in transfer fees and 5 million additional bonuses has been rejected by Werder Bremen.
Ajax has made a second offer, with a basic transfer fee of 9 million euros and a bonus of 3 million.
Werder Bremen asked for a transfer fee of 15 million euros, which was also the cost of signing Klassen from Everton.
The transfer can still be completed through negotiations, Werder Bremen hopes to raise funds.
