According to D’Amico, a move to Napoli will profit the Nigerian striker better.
Liverpool are believed to be among the Premier League clubs reportedly making a last-ditch attempt to snatch Osimhen.
However, D’Amico who is involved in negotiations with Napoli, has played down talks of a transfer to England.
When asked if Napoli manager Gennaro Gattuso liked Osimhen, he told Football Italia: “Very much, he likes all good players. The Giuntoli-Gattuso axis is making Napoli stronger and stronger.
“The right step for the attacker (Osimhen) is Napoli, not Liverpool”.
