Relegated Hull have released longest serving players Paul McShane and Liam Rosenior as they reshape their squad.
Real Madrid have vehemently denied reports they have made an approach to sign Juventus midfielder Paul Pogba.
Napoli president Aurelio De Laurentiis anticipates a decision on the future of Edinson Cavani before he returns to Italy at the end of July.
Chelsea and Real Madrid have both been linked with a summer move, while Manchester City have decided not to meet his €63million (£54million) buyout clause.
That clause in Cavani's contract expires on August 10, which has led to speculation he could wait until then to leave Napoli in order to secure a better deal for any future club.
But De Laurentiis thinks the Uruguay international, who is currently in Brazil at the Confederations Cup, will decide his future before he returns from a summer break on July 20.
De Laurentiis told Radio Rai: "I don't think Cavani will leave on August 10, when his buyout clause expires.
"I'm confident in him, because I consider him a real man. He won't make me a joke of me.
"Should Cavani want to leave, he will decide it after a long period of reflection.
"But by July 20 we will probably know everything about his future."
