Uefa is set to announce today that video assistant referees (VARs) will be introduced into the Champions League halfway through the tournament. After the match, the president of the Italian referees' association issued a statement admitting an error had been made.
It will ensure that at least 34 countries will be represented in UEFA club competitions, compared to today's total of 26.
After the group stage, there will be a knockout round for UEL2 runners-up and the third-placed finishers in the Europa League to determine who advances to the round of 16. The plans were approved by the UEFA executive committee on Sunday, three years after the initial discussions were first revealed by The Associated Press.
The format will see eight groups of four teams, followed by the round of 16, quarterfinals, semifinals and final.
"We are ready to use VAR earlier than initially planned and we are convinced that it will be beneficial for our competitions as it will provide valuable help to match officials and will allow us to reduce incorrect decisions", said Uefa president Aleksander Ceferin.
Every country's champions will still enter the Champions League, but only teams from the 15 top-ranked countries will go into the Europa League group stages or qualifiers.
Discussions have been in place for some time regarding the possibility of introducing a brand new European competition to the footballing schedule which would offer more teams the opportunity of being able to play in Europe.
"There was a widespread demand by all clubs to increase their chances of participating more regularly in European competition". This could be an important if UEFA confirm what is already known behind the scenes, that VAR is coming very soon to the Champions League.
The introduction of the new tournament does not affect the Champions League's format at all.
