Chelsea is allegedly eager to sell Hakim Ziyech this summer for the right price.
The 28-year-old was a regular for the Blues in his first season, appearing in 39 games across all competitions, but he only scored six goals and four assists in a disappointing campaign.
Meanwhile, Ziyech has only scored twice in 23 Premier League appearances, and Napoli has been linked with a move for him.
Chelsea would be willing to move the Morocco international during this summer's transfer window if they got a decent offer, according to Calciomercato.
According to the source, both AC Milan and Napoli are keeping a careful eye on the situation surrounding Ziyech, who has more than four years left on his current contract.
The attacker was an unused substitute in Manchester City's 2021 Champions League final, which Thomas Tuchel's side won 1-0 thanks to Kai Havertz's goal.
