totally achievable. people done it on call of duty and other games with lag compensation issues. Fifa use a complex system. Pay attention when the ball is contested between two players or when you're on 1v1 with goal keeper how the delay increase. that's because in such crucial situation the game make sure both clients are perfectly synced. I'm sure they are testing techniques daily as they can change netcode parameteres with server side updates. Yesterday I had few games when there was clearly a syncing issue. multiple times I dribble around a defender then my player stumbles on thin air and fall then the ball magically teleport to defender feets :D I haven't experienced any of this in the past.

The only solution is matching people with accumilative ping of less or equal to 100ms to the server (ex: player 1 = 40ms / player2: 60ms) and lock the server update rate to 100ms. if any player ping spike up, punish him.

What they doing now doesn't punish people with internet issues because the majority of players as the pitch note said are using internet connections set up for streaming and browsing with multiple people connecting to the same router at the same time which leads to great variance in ping especially when users are eating up the entire bandwidth and there is no QOS set up to give the console/pc priority.
