Jose Callejon has a €23m release clause with Milan and Atletico Madrid interested in the Napoli winger.
The 31-year-old has been at the Stadio San Paolo since 2013, but could be open to moving on after Maurizio Sarri was replaced by Carlo Ancelotti.
He was practically ever-present under Sarri and this season scored 12 goals with 17 assists in 50 competitive appearances.
According to La Gazzetta dello Sport, Atletico Madrid and Milan are both eager to sign the Spaniard.

According to La Gazzetta dello Sport, Atletico Madrid and Milan are both eager to sign the Spaniard.
His €23m release clause is valid for clubs both inside Italy and abroad.
Atleti would be a return home to Spain and Madrid, as he played for their rivals Real for most of his career.
Before making such an investment, Milan would need to wait and see what verdict UEFA hand down for the Financial Fair Play investigation.
