What is the difference between American football and European football?


assistant
American football and European football are two different sports. American football, also known as gridiron, was first played in 1869 in the United States and mostly known in the United States and Canada. It rivals two teams on a rectangular field. Both teams have an offence as well as a defence formation. The first offence and defence of the match is decided by coin tossed where the winner decide for the first half of the match while the opposite match starts at the half-time mark. The offence team tries to take the oval-shaped ball to the other side of the field by passing or running it at each play. The defence team blocks the offence team so they get the balls themselves either by steeling it or when the offence team hasn’t progressed 10 yards in 4 plays. Then, offence team becomes defence and vice versa. When the offence team successfully reach the 10-yard lines, they obtain a new set of 4 plays to get to the endzone, where they obtain points when succeeding, called a touchdown. They also get points from kicking the ball within the goalpost. The winning team is the one with the most points at the end of the game. European football, also known as soccer, is a match between two teams of eleven players on a rectangular field, known as pitch. Players primarily use their feet to propel a sphere-shaped ball across the field into the rectangular shaped goal guarded by a goalkeeper. The goalkeeper is the only player of each team that can use his hands and arms on the ball within a specific region of the field close to their goals. The game is played continuously until a fault is committed or the ball exits the field. Each team tried and kick the ball in the goal to get points and the winner is the team with the most point at the end of the match.
