Nice are appealing to find a supporter who was spotted wearing one of their shirts during Bournemouth's Premier League match against Leicester, reports Sky Sports.
Like Bournemouth, Nice play in red and black stripes and the fan can be seen wearing their shirt from the 2002/03 campaign.
The French outfit have since made an appeal on their official Twitter account and have offered the supporter the chance to visit the Allianz Riviera.
Their tweet read: "Can you help us to find this man please? He will receive an invite to join us at the @AllianzRiviera."
