The released audio revealed the conversation between on-field official Busquets Ferrer and VAR Mario Melero Lopez.
Lopez initiated the review by recommending a review, telling the referee to check for a "possible cancellation of the red card you have shown, please". He followed up by suggesting the contact was a "natural dynamic" after the Barcelona man played the ball in a normal fashion.
After reviewing the footage at the monitor, Ferrer was swayed by the VAR's interpretation, stating Martin "plays the ball and then steps on him, normal dynamic. I am going to cancel the red and show him yellow, okay?"
The CTA has now ruled that this recommendation should not have been made “as it was a correct decision made by the referee on the field".
