Spanish television claim Napoli wide attacker Jose Callejon will join Atletico Madrid this week for €15m.
According to TVE, a deal is imminent between the two clubs.
Callejon joined the Partenopei two years ago from Real Madrid, suggested by then-Coach Rafa Benitez.
Selling the Spaniard for €15m would represent a tidy profit for Napoli.
New Coach Maurizio Sarri has already brought in Mirko Valdifiori from Empoli.
There are several players who do not fit into his plans, including Callejon and Belgium international Dries Mertens.
Callejon has scored 32 goals and provided 18 assists in all competition for Napoli during 111 appearances.
His performances in Serie A helped earn him two senior Spain caps.
