Guerreiro should have been sent off for foul on Luka Modric
Although there was little discussion of the incident afterwards, surely there is a case to be made that the Dortmund midfielder should have seen red.
It was the 77th minute of an open encounter in the second round of group games in the Champions League 2016/17. Real Madrid were playing in their hardest match of the group - away to Borussia Dortmund - and had forged a 1-2 lead just 10 minutes earlier thanks to Varane.
What a chance for Madrid
Should Dortmund have been reduced to 10 men?
Let's have a quick flick through the Fifa rulebook to Law 12 where it states: a player is sent off if he denies an obvious goalscoring opportunity to an opponent moving towards the player’s goal by an offence punishable by a free kick.
Modric, and teammates were certainly moving towards the player's goal. Tick. It was an offence punishable by a free kick. Tick. So the question is simple: did Guerriero's deliberate foul deny Madrid an obvious goalscoring opportunity? I believe so.
Many have thrown this argument out though saying "dangerous" doesn't mean "obvious" and they're right. But if we'd had the ability to freeze that moment in time (just before the foul), looked at the situation opening up and asked a selection of professionals and knowledgeable fans what the chances were of an obvious goalscoring opportunity resulting I think most would say likely.
To appease a couple of other arguments that I've heard, the rules confirm that this offence does not need to occur inside the penalty area. Also, referees are asked to consider the following which I've added my thoughts in brackets:
In the end, the result was a fair one but when has that removed the need, or desire, to discuss decisions that can be interpreted in a variety of ways.
