The former Fulham midfielder is understood to have agreed personal terms with AEK however Portsmouth’s administrator Andrew Andronikou will not sell if their valuation of the player isn’t met.
He told The News: “Athens are making noises and I have been in direct contact with them.
“They know our position and they know they have to write a cheque. Unfortunately that has not happened yet.
“Diop is available for 1million euros and if they want him they will have to pay that amount. We have absolutely no intention of giving him away.”
