This technology bases in the video of assistance of arbitration.
The VAR already implanted in the last World-wide contested in Russia and, in spite of that saw a lot of things mejorables, in general lines worked with correction. Other competitions like LaLiga Santander approved the use of the videoarbitraje to reduce the errors of the referees and apurar better in the controversial decisions.
The oddest of all was that the UEFA had not given the consent to use the VAR in a so important competition like the Champìons League and that sometimes has arrived to decide by erroneous decisions. Nevertheless, it has rectified said decision and the president of the UEFA, Aleksander Ceferin, confirmed that there will be VAR from eighth of final of the League of Champions.

"We are smart to use the VAR before the initially planned and are convinced that it will be beneficial for our competitions, since it will provide a valuable help to the referees and will allow to reduce the number of wrong decisions", commented Caferin.
The decision was very necessary, since in the maximum competition of Europe to level of clubs were seeing referee's errors so bochornosos like the penalti signalled in favour of the Manchester City after a ridiculous fall in the area of Sterling, extreme of the team 'cityzen'. From eighth, will cost to see failures of that calibrate.
