"The European Judo Union has voiced its severe disapproval of the tackle, likening the tackle to the waki-gatame manoeuvre – which is banned in the sport when used in transition from a standing position to the ground, due to its ability to severely injure opponents.
The Union’s official Twitter account posted an image suggesting Ramos used the “forbidden arm-lock technique” to bring down Salah:
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?"
