Fulham have agreed a deal with Ajax to sign Calvin Bassey for £18.2m and are in talks to add Mohammed Salisu from Southampton.
Centre-back Bassey was willing to stay and fight for his place but Ajax have told the 23-year-old he does not figure in their plans.
Ajax manager Maurice Steijn said: 'I told Calvin Bassey it would be better to leave Ajax. Also because of the money. When he leaves, we can strengthen the squad properly.
'I have told him this honestly. He had a really tough year last season. Everyone gets a second chance and if he does better than someone else, he will play.
