The Dutch midfielder recently did not enjoy the confidence of Everton coach Sam Allardyce, because the transition to Napoli is seen for him as a good option.
According to Tuttomercatoweb, the clubs have already agreed the terms of the deal, while Klaassen also gave the go-ahead for the transfer and stipulated the details of the personal contract.
Nevertheless, the transfer can be hampered by a problem with image rights, which is very common in the transition of players in Napoli.
The president of the club Aurelio De Laurentiis usually likes to make the most of the image rights of newcomers to whom he sets the condition to cancel all his sponsorship deals before moving to Napoli. Often this leads to the fact that transfers eventually fail.
This season, on the account of Klaassen only 4 matches in the Premier League.
