Neco Williams' early red card meant Wales had to toil for more than an hour with 10 men as they were beaten 3-0 by France in their first friendly in preparation for Euro 2020.
The visitors' already daunting task of facing the world champions on their own turf in Nice was made even more onerous when Liverpool youngster Williams was sent off just 25 minutes into the match, after a VAR check deemed his handball had illegally impeded a goal-bound effort from Karim Benzema.
Benzema, making his first international appearance for almost six years, had his penalty saved by Danny Ward, who then did well minutes later to keep out Adrien Rabiot's deflected shot before Kylian Mbappe scored on the rebound.
