Agent Mario Giuffredi has hinted that Elseid Hysaj's proposed move from Napoli to Chelsea is still on.
Napoli were keen to keep the 24-year-old at the club, however, and president Aurelio De Laurentiis suggested last week that a contract renewal will be discussed.
However, the emergence of Kevin Malcuit, coinciding with Hysaj's loss of form, has led to the player's representative talking up a big-money move to Chelsea.
"Chelsea in for Hysaj? If you see Napoli are playing Malcuit and looking at other players, clearly it means that there are also enquiries," Giuffredi told Radio CRC.
"Those who say otherwise are misinformed. Hysaj is a player who can do well in English football, given he's very physical and being watched by big clubs. Is he worth €50m? He's worth €60m for me."
Sarri coached Hysaj in Italy with both Napoli and Empoli.
