What Constitutes a Foul in Football?
As a rule, a football foul would be an unfair act committed by a player which interferes with active play. A match referee would decide on the foul while officiating the game's laws.

There are different outcomes that punish soccer fouls. The referee can award either a direct or an indirect free-kick (depending on the offence). In some cases, a foul in football results in a penalty spot kick awarded to the opposing team.
