Napoli president Aurelio De Laurentiis has confirmed his club's interest in Porto forward Jackson Martinez.
De Laurentiis took to Twitter to respond to speculation linking the Serie A side with a number of players around Europe, including Paris Saint-Germain's Marco Verratti.
De Laurentiis said: "We are a friend of Paris Saint-Germain and Verratti is not for sale.
"The player's agent is trying to put pressure on Paris Saint-Germain in order to gain a pay rise, but we do not go along with these games.
"We are searching for the right reinforcements in attack. It may be Martinez or it may be another. Our manager Rafael Benitez will decide."
Benitez has had a busy start to his reign as Napoli manager and has already lost star striker Edinson Cavani to PSG.
One player linked with replacing Cavani is Brazilian Leandro Damiao, but Internacional president Giovanni Luigi says that they have not received an official offer for the player.
Speaking with Radio Gaucha, Luigi said: "Leandro Damiao is focused. There has been no contact in the last days.
"They talked about Napoli, but nothing official has come."
The Sky Blues, who have left the Ricoh Arena after becoming embroiled in a bitter rent row, will play at Northampton's Sixfields Stadium for the next four years while they build a new home in the city.
And the first steps have already been taken after the club agreed terms on a site six miles outside the city centre.
The club, who are hopeful of finalising the deal within eight weeks, have also entered exclusive talks over a second location.
Chief executive Tim Fisher said: "We completely understand the pain the groundshare is going to cause our supporters but we have a clear path to return to the Coventry area.
"We are under no illusions at just how tough it is going to be for the next three years but there is absolutely no question that Coventry City Football Club's long term future is in this area.
"Once we have agreement on a site, we will begin a consultation process with our supporters because we want this to be their home - a home that everyone can be proud of.
"And, of course, a home where the club has access to all matchday and non-matchday revenues which are crucial when it comes to financial fair play."
The Sky Blues have already recruited a number of companies with high-profile projects in their resume to help with the process, including AFLS+P, architects of the New York Stadium in Rotherham, whose relocation back to the town from Sheffield is a model that Fisher has already identified as one to emulate.
