In detail what VAR does in the phases for which there is a suspicion of offside.
Technology may now have entered football for good, in order to reduce the wrong decisions of the referees that lead to injustices, but this does not mean that the protests about phases that use the VAR. Even if we are talking about its simplest use, that of… drawing its lines offside.
Something, as one can easily understand, is not done manually. In other words, they don’t take from it VAR a ruler and draw a line on the attacker and one on the defender in order to conclude whether or not the former was exposed.
Such as FIFA has also explained with a relevant video which she has posted on her official account before 5 years, the two sides of the field join the lines somehow automatically. What is done manually is the definition of the body point through which the line will pass to the last player of each team.
Commonly crooked lines cannot exist and if in some replays that we see in the games, we are given this impression it is because the point defined as the last of each player’s body is made with two lines. One horizontal and one vertical.
To understand, watch the following video published by Mark Clattenberg three years ago and explains the process step by step with a real example from his game PAS Ioannina by Olympic.
Finally, it is worth noting that the specific system used in the matches in Hellasis also certified by UEFA and from FIFAwhile it is the same as that in Portugal.
