The Irish U20s take on France U20s in the JWC fifth place play off on Tuesday night at Stade Henri Desgrange in La Roche-sur-Yon.
In the semi final the 24 year old scorched in for two superb tries and was replaced immediately after he added the conversion of the second, to be kept fresh for the final.
It proved a clever ploy as Manning played a central role in what was a close final and a tense finish.
Manning also scored a try in the earlier round game against Leicester Tigers.
In the main event London Irish were beaten 15-12 by the Samurai side.
