This is not good news, especially on the back of Bruno's retirement. I couldn't see Stephens or Kayal getting much gametime at Ajax, and I would like to see Propper play under Potter.
What's relevant here is Dusan Tadic. Bought in 2014 by Southampton from Twente for c. £10 million, sold to Ajax 4 years later for c. £10 million. 20 goals in 134 games for the Saints, 20 goals in 27 matches for Ajax.
I'm sure having put that amazing deal together Ajax would like to come back...
