There is absolutely nothing wrong with headers and crosses this year it’s pretty much spot on as to how it should be I have absolutely no problem scoring them nearly every game I play
As it takes some sort of effort to learn/do the majority of fifa players simply refuse to and of course they have to change out their small fast forwards to do them unlike before when they could outjump tall defenders at the back post with ease

Manual crossing definitely helps with the right players up top who actually have jumping and heading stats
