The award was for the Frenchman’s contributions to football in Africa.
Wenger found Weah playing for Cameroon’s Tonnerre Yaounde and took him to French team Monaco in 1988.
Weah was later to become World Footballer of the Year and won the Ballon d’Or in 1995, the only African to have done so.
Speaking during the event, Weah said: “You [Wenger] proved yourself as a teacher when you revolutionized forever the approach of scouting young talents all over the planet, particularly throughout Africa.”
Wenger was named a Knight Grand High Commander of the Humane Order of African Redemption, the highest rank in Liberia’s Order of Distinction with Claude Le Roy getting the same award.
