Napoli captain Kalidou Koulibaly has hailed the progress of Victor Omishen over the past 18 months.

Koulibaly says the Nigeria striker is now one of the key strikers in Serie A.

He told DAZN: "If I were to make a biopic about Victor Osimhen, I would tell about his first year which was very difficult. Nobody expected that he would get to the level of today, but he still has a lot to give and he will still show a lot of things both this season and in the future.

"He is a very calm, humble boy and even makes you laugh. He plays a lot of jokes, especially on (Kostas) Manolas, then after the goals he dances with (Lorenzo) Insigne: he is a extraordinary person, I want to help him in his growth because he deserves it.

"He always makes himself available to everyone, I tell him chapeau.

"(Luciano) Spalletti pushes him a lot, as soon as he arrived he immediately told him what he was doing well and what not. But it was (Rino) Gattuso who helped him a lot, too. Last year gave him a lot of confidence. Then Spalletti completed the work by helping him a lot, this combination bears fruit today."
