Was the referee’s decision correct?! Barcelona player shown a red card

In the first leg of the UEFA Champions League quarter-final, Barcelona host Atlético Madrid, and a contentious incident occurred late in the first half.

Details: In the closing minutes of the first half, a Barcelona player brought down an Atlético Madrid attacker who was through on goal with a clear one-on-one opportunity against the goalkeeper. Initially, the referee showed a yellow card, but after a VAR review, he changed his decision and sent off Pau Cubarsí.

Reminder: The Champions League quarter-final against Barcelona got off to a poor start for Atlético Madrid, with a significant personnel loss.
