Argentina international striker Gonzalo Higuain will not leave Napoli this summer, according to club president Aurelio De Laurentiis.
Higuain has been linked with a move to the Premier League, with Chelsea, Arsenal and Manchester United thought to be keen to acquire the 27-year-old's services.
The former Real Madrid star has three years left on his contract with Napoli and the Serie A club have no intention of letting him leave.
"There is absolutely no chance that Higuain will leave," De Laurentiis told Italian TV station Mediaset. "Gonzalo is a Napoli player.
"I have made his (release) clause clear in order to stop the constant speculation that appears in the press.
"There is a precise clause."
Napoli paid Real Madrid €40million to sign Higuain in the summer of 2013 and any potential suitors would have to splash out €94.7million, Higuain's release clause, to acquire the player.
Higuain has been Napoli's top scorer in the past two seasons. He struck 18 goals and set up seven more in 37 league appearances for Napoli during the 2014-15 campaign.
Higuain is on holiday after helping Argentina to the Copa America final earlier this month but is expected to join Napoli next week to begin work under new coach Maurizio Sarri.
"Higuain played in the Copa America he has the right to a certain number of days off," De Laurentiis said.
Napoli finished fifth in Serie A in 2014-15 and will play in the Europa League next season.
Stoke have announced the signing of winger Moha El Ouriachi from Barcelona for an undisclosed fee.
El Ouriachi, who has represented Spain at youth level and has been called up by Morocco's under-23 squad, could make his first appearance in the Potters' Asia Trophy game against Everton in Singapore on Wednesday.
The Barclays Premier League side have not announced the length of the 19-year-old's contract.
"Stoke City are pleased to confirm they have completed the signing of Moha El Ouriachi and he could make his first appearance for the Club in today's Barclays Asia Trophy tie," the club said in a statement on their official website.
"Moha turned down Barcelona's offer of a new contract in favour of a move to the Potters, where he links-up with ex-Barca players Bojan and Marc Muniesa.
"Moha is now clear to figure in the Asia Trophy game against Everton in Singapore, which kicks-off 6pm local time (11am BST)."
Stoke chief executive Tony Scholes added: "He's excited about joining a Premier League club, especially one that already has two former Barcelona players in their squad.
"Moha has seen the progress made by Bojan and Marc and wants to try and do likewise."
Dynamo Kiev midfielder Jeremain Lens is expected on Wearside for a medical on Wednesday amid mixed news on the transfer front for Sunderland head coach Dick Advocaat.
The Netherlands midfielder was heading from Ukraine to the north-east on Tuesday night after the two clubs agreed a fee in the region of £8million.
However, as the Black Cats prepared to push home their interest in the Dynamo man, sources close to the club have indicated that their interest in Zenit St Petersburg defender Nicolas Lombaerts has been shelved because of an issue picked up by medics.
Rumours that the 30-year-old Belgium international had failed a medical began to circulate on Tuesday evening, and it is understood that a proposed £5million transfer has now been put on hold.
But if that came as a blow to Advocaat, whose side lost 1-0 to Sacramento Republic in the United States during the early hours of Wednesday morning, the news on Lens is far more encouraging.
The 27-year-old, who worked under his compatriot at both AZ Alkmaar and PSV Eindhoven, watched his current club's 2-0 Ukrainian Super Cup defeat by Shakhtar Donetsk in Odessa from the stands on Tuesday evening before setting off for England.
Sunderland are hopeful of concluding a deal within days to allow the player to meet up with the rest of the squad in America.
