Me ent know what kinda football alyuh men does play...but that what them fellas doing in that video is real 4kin skill.
That is a driven shot from the 1/2 line to the 18 and the target is just a lil bigger than the circumference of the ball. the man that miss come like he hit the post.
Plus the ball rolling too...men ent sure too much men on we national team could do that.
But to answer the original question...A strikers wuk or training does really begin at the end of the training session when he bun...or when he doing shuttles and hard sprint. Is one thing to score when yuh fresh and under no pressure...is a totally different ting to score when yuh bun and have a man on yuh.
Sometimes they will line up the balls and have you hitting bullet, when you ready to drop down while doing shuttles or they will place cones in the post and have you aim for that..or they does put a defender on yuh back and tell the defender stop him using any means.
Shearer and Owen used to hit 100 placed shots into the goalpost corners both right and left foot after every training. They had a documentary about that online on BBC sport.
Is repetition, muscle memory, habit, grit and determination.
Scoring goal is a art...you either have it or you dont and composure and luck is a big factor. The ability to get into a goal scoring position is another art plenty men ent have.
