Manolo Gabbiadini joined Napoli in 2015 from Sampdoria

Everton are in talks with Napoli to sign Italy forward Manolo Gabbiadini, according to Sky sources.

It is understood the Italian club want £25m for the 24-year-old and several reports in Italy claim the Toffees have already had a £19.6m offer rejected.

Gabbiadini signed for Napoli in January last year for £10.2m from Sampdoria and has scored 20 goals for the Naples club.

He was not part of Italy's squad for Euro 2016 but he has earned six caps for his country, the most recent in September 2015.

Ronald Koeman is keen to bolster his squad further before the transfer deadline

Everton, backed by wealthy new ownership, have spent significantly in the transfer window so far this summer - over £50m on five new players - and they are still looking to strengthen before Wednesday's deadline.

They are hoping to sign a new winger-forward. Gabbiadini began his career at Atalanta and signed for Juventus in 2012 but was shipped out on loan to Bologna and then sold to Sampdoria in 2013.
