The race for Lille defender Gabriel is becoming a straight shootout between Arsenal and Napoli.
Manchester United were also keen, but are now focusing on other targets, reports Le 10 Sport.
Gabriel is said to have agreed terms with Napoli, but Arsenal remain in the hunt.
Both clubs have had offers of €30m accepted by Lille, with the final decision left to Gabriel.
A decision from the Brazilian could be announced in the coming days.
