The transfer from French side Lille to Napoli was reportedly worth around €80 million, and it took place during the COVID-19 pandemic. Osimhen stated that he was not fully aware of the negotiations and did not receive proper documentation. He also expressed frustration with his agent, Jean Gerard, who he felt was only interested in the transfer and not in his father's well-being.

Osimhen shared his story in testimony given to Italy's Guardia di Finanza. He described how his agent, Gerard, called him to meet in Nice and told him that he should move to Napoli. Osimhen was not given the opportunity to see his father before his passing, and he felt that Lille and his agent were prioritizing the transfer over his personal situation.

Osimhen eventually met with Napoli's coach and president, Aurelio De Laurentiis, in Capri. However, he claimed that he would not have signed the deal if he had been given the opportunity to read the contract and understand the terms. He also felt that the negotiations were "brutal" and left him feeling "extremely angry."

Osimhen's experience highlights the complexities and challenges that can arise in professional sports, particularly when personal and family circumstances are involved.
