Enoh joined Fulham in January and spent the latter part of the campaign on loan at Craven Cottage.
The 27-year-old featured nine times and impressed in midfield for Martin Jol, who is keen for him to return.
However, Jol is not willing to match Ajax’s price tag – believed to be near £3million.
Enoh’s agent Stephan Brandli confirmed to Sky Sports that talks were ongoing between the two clubs.
“As I understand there have been talks between the two clubs, however, Martin Jol, who knows Ajax very well, is not willing to pay the current price,” Brandli said.
“Eyong enjoyed his time at Fulham and did well, and of course he would love to go back.
“Ajax coach Ronald de Boer has gone public to say that Enoh can leave, and he does not want to sit on the bench at Ajax so he is hoping that something can happen.”
Brandli did admit that there was interest from elsewhere in England, and added: “We have heard of a few more teams in the UK are interested.”
