How can he have aimed it at the keeper if the keeper is moving?
All these arguments about it being a poor finish are based on a scenario where the Palace keeper is standing still, he isn’t though, he’s moving back across the goal.
So Beto has to make the run, time his leap, and direct his header downwards with power. Now he’s supposed to also anticipate how far across the goal the keeper might be able to get back in time?
Ultimately if Beto doesn’t do any of those first four things there’s no goal.
