Champions League quarter finals get underway on Tuesday night as four English clubs prepare for their games. Tottenham will take on Manchester City, while Liverpool will host Porto and Manchester United will play against Barcelona at home.
After UEFA approved Video assistant referees introduction in December, VAR will be used in the last stages of the Champions League.
During the ties, referees will be able to make use of the system to review goals, penalty decisions, direct red card incidents and cases of mistaken identity.
Also the teams will have to be aware of the away goal rule. The UEFA statement reads: “For matches played under the knockout system, if the two teams involved in a tie score the same number of goals over the two legs, the team which scores more away goals qualifies for the next stage.
“If this procedure does not produce a result, i.e. if both teams score the same number of goals at home and away, two 15-minute periods of extra time are played at the end of the second leg.
“If both teams score the same number of goals during extra time, away goals count double (i.e. the visiting team qualifies for the next stage).” (via Mirror)
Manchester United have already benefited on away goals as they made a comeback against PSG in the round of 16.
