Everton will not sell striker Richarlison, manager Rafa Benitez said on Friday.
He joined Newcastle from Belgium's Anderlecht in 2015 and made 59 appearances for the English club, including 11 last season.
The Spaniard took charge of Newcastle in 2016 and helped them earn promotion from the Championship.
Newcastle had a great run in their first season in the Premier League after getting promotion from the Championship.
Newcastle United owner Mike Ashley put the Premier League club up for sale on Monday, signalling an end to his decade-long reign at St James' Park.
Benitez believes in Spanish players and their ability to adapt to his strategy.
