The former striker saw his record as the club's youngster ever scorer taken away from him on Saturday as Kylian Mbappe netted in injury time against Troyes
A 17-year-old Henry scored his first ever professional goal as Monaco triumphed 6-0 over Lens on April 29, 1995.
Henry, who is now retired, held that record for just under 21 years, until Mbappe scored in the 90th minute as Monaco ran out 3-1 winners over Troyes at the weekend, trumping the World Cup winner by a matter of months.
Mbappe was not even born when Henry opened his Monaco account, coming into the world over three and a half years later and has already been linked with a move to Real Madrid, Liverpool... and Arsenal.
The youngster made his debut against Caen earlier this season, before grabbing his first assist in the 4-1 loss to Tottenham in the Europa League in October.
