Chelsea have offered £43million for Ajax defensive midfielder Edson Alvarez.
The Dutch champions are refusing to sell any more of their squad this window. However, Mexico international Alvarez, 24, wants Ajax to consider the offer as he fears the chance to move to Chelsea may not arise again.
Ajax have already sold Lisandro Martinez and Antony to Manchester United and had earlier told midfielder Mohammed Kudus that he could not join Everton despite the Ghanaian refusing to train.
The Dutch transfer window closes earlier than the rest of Europe at 11pm UK time on Wednesday.
