Salah dislocated his shoulder in the scuffle, and was forced off the pitch in tears with the score at 0-0, thus throwing his participation in the World Cup into serious doubt.
Waki-gatame is a dangerous technique. That's why it is not allowed in Judo to use for transition to ne-waza. What do you think about this foul yesterday evening in the #UCLFinal between #RMALIV ? pic.twitter.com/mHmADyG7LB — European Judo Union (@europeanjudo) May 27, 2018
So divisive has the tackle been, fans have set up a petition calling for Ramos to be punished, which currently has over 300,000 signatures, while an Egyptian lawyer has launched a €1 billion (£873m/$1.2bn) lawsuit against the centre-back.
And now another sport has weighed in on the controversy, the European Judo Union insisting that Ramos's move would be deemed illegal in their circles.
"Waki-gatame is a dangerous technique," they wrote on Twitter. "That's why it's not allowed in Judo to use for transition to ne-waza. What do you think about this foul yesterday evening in the #UCLFinal between #RMALIV."
Watch out, Sergio Ramos!
The Real Madrid defender has angered quite a few people following his collision with Mohamed Salah. 😮
