The midfielder has so far struggled to impress at West Ham United.
The midfielder has struggled to settle at West Ham since his arrival from Sampdoria last summer.
He managed just 24 appearances in the Premier League, totalling 1079 minutes, as a solid midfield partnership between Mark Noble and Cheikhou Kouyate kept him out of the side.
A return to Italy could now be on the cards, with Napoli reportedly putting him on a shortlist of potential signings.
They are keen to strengthen the midfield this summer, and are targeting a deal with Fiorentina for midfielder Matias Vecino.
That potential deal is looking hard to get completed though, and according to CalcioMercato they have identified Pedro Obiang and Roberto Soriano as alternatives.
Whether West Ham would be willing to sell is as yet unknown, although it would be fair to suggest they will not be.
The Hammers have enjoyed a fine first campaign under manager Slaven Bilic and will surely be keen to keep hold of the majority of their squad.
Indeed, Bilic has already hinted he is only hoping to make a couple of additions this summer, suggesting that he is not anticipating letting anyone leave.
