The recent Madrid derby once again made headlines for its many controversies, including a couple of questionable refereeing calls that completely sided with Atletico Madrid.

Perhaps the biggest of them all was Kang-in Lee’s challenge on Federico Valverde, which left the Real Madrid midfielder pick up an injury that will keep him out for a few weeks .

Lee’s challenge was blatant and dangerous and in any other day, the Atletico Madrid player could have easily gotten a red card. That was not the case here.

Now, according to the Technical Committee of Referees (CTA), Kang-In Lee should indeed have been dismissed for the dangerous challenge on Valverde just before half-time, reports AS .

“ Direct free kick and red card. Clear and manifest error of the referee. The VAR should have intervened,” the CTA confirmed.

It represents a notable admission of fault, with the officials acknowledging that both referee Ortiz Arias and the VAR failed to correctly punish an action deemed serious foul play.
