Tang Long was able to discern the reason for Gerrard disguising his left foot injury, mainly thanks to the strong analytical ability of his AI system and its keen attention to detail.
Although Gerrard's left ankle was only slightly sprained, such an injury was enough to affect his movements and performance in a fierce match.
Specifically, after a player sprains his ankle, to alleviate pain and protect the injured area, his movements will undergo a series of changes.
For example, while running, he may reduce the pressure on the left foot upon landing and avoid using the left foot for intense confrontations or directional changes;
When passing and shooting, he might also prefer to use his right foot.
These subtle changes, though possibly unnoticed by the naked eye, could easily be captured and analyzed by Tang Long's AI system.
During the first 40 minutes of the match, Tang Long was closely observing Gerrard's movements.
