Serie A champions Juventus are set to offer €40m to seal the services of Marek Hamsik away from Napoli, reports Tuttosport.
The Slovakia international has a contract with Napoli until 2018 and club president Aurelio De Laurentiis is willing to offer Hamsik a new deal to stay at the Stadio San Paolo.
"Will Marek will stay at Napoli? Everything is possible,” Hamsik's agent Juraj Venglos told Gazzetta dello Sport.
“At the moment probabilities are at 50 per cent.”
Hamsik will definitely play against England at Euro 2016 tonight as Slovakia hope to seal a place in the second round of the tournament.
