Jackson Martinez’s agent has revealed that Napoli have an agreement with the player but convincing Porto to part with their star forward will be difficult.

The Partenopei have made it clear they are looking for another world class forward to add to their ranks and the Colombian hitman is reported to be at the top of that list.

“There is an agreement with the player,” Manuel Manzo told Sky Sport Italia. “However, one with Porto is missing and they don’t want to sell.

“The only chance of a move happening, in my opinion, is if the Azzurri pay the €40 million rescission fee clause which is in his contract. Otherwise he won’t move.”

Napoli are reportedly willing to bid €32m for the South American.

The 26-year old was prolific for the Portuguese giants last year and is keen on a move to Italy but Porto are notorious for their steep transfer demands.
