Napoli are looking for new faces to replace Gonzalo Higuain, a Gunners target, who has joined Juventus.
They are set to sign Arkadiusz Milik from Ajax but Giroud has been described as a cut above.
Aronica, who made more than 100 appearances for Napoli between 2008 and 2013, told Tuttomercatoweb: "If Napoli want to reduce the gap with Juventus they should aim for a top player.
"Without detracting from the young Milik and Gabbiadini, they need a major impact to reinforce the attack. A great choice could be Giroud, a player who has much international experience and that would raise the bar."
Giroud is a player who gets his share of flak from French fans and some Arsenal supporters who believe the club need better, but these comments serve as a reminder that he is a player at a high level who may simply be under appreciated.
The striker was linked to Napoli in July, with his agent playing down rumours, via The Guardian, and it would be a surprise if Arsenal were to sell him, considering their own struggles buying a striker this summer.
