Napoli president Aurelio De Laurentiis expects negotiations over the sale of Edinson Cavani to Chelsea to begin imminently.
Uruguayan striker Cavani has been linked with a move to the London club as new manager Jose Mourinho looks to strengthen his side after taking over for a second spell in charge.
The UEFA Europa League winners will need to activate a 53 million-pound release clause to bring the 26-year-old to Stamford Bridge.
However, that does not appear to be a stumbling block for Mourinho, with De Laurentiis stating that he is anticipating an approach from the Premier League club.
"The budget for the transfer market will be based in relation to the Financial Fair Play rules," De Laurentiis told Radio Marte on Friday.
"If Cavani is sold then I'll reinvest all of the 53 million of his rescission clause. There is interest from Chelsea in Cavani, they'll call me in the next few hours.
"I'll be delighted if he stays, but if he leaves then he will be adequately replaced."
Chelsea's strikers largely struggled last season, as although Fernando Torres scored 22 times in all competitions, just eight of those coming in the league.
Demba Ba was signed from Newcastle in January, but found the net on only eight occasions as he failed to replicate his early season form with his new club.
Cavani has made 136 appearances in all competitions for Napoli, scoring 104 goals.
