McKennie and Weah were both deployed out of position, with the former being put in an attacking minded role on the wing instead of central midfield. Weah, meanwhile, was put as a fullback during the first 55 minutes before pushing further up the field due to a tactical adjustment.
Neither American truly stood out, but by the time Weah was given a chance in the attack, they were already down three goals. McKennie, meanwhile, was creative in moments but struggled in a wider position.
Motta will be questioned for his tactical choices as their top-four hopes took a hit. Just nine Serie A matches remain on the calendar as the club looks to clinch UCL for next season.
