The VAR, John Brooks, deemed that Dias had tripped Ramsey, and the referee, Craig Pawson, initially let play continue. However, after reviewing the incident, the VAR recommended an on-field review, which resulted in the penalty being awarded to Aston Villa.
The Premier League has explained the decision, stating that the VAR checked the initial call of no penalty and found that there was a clear trip by Dias on Ramsey. The referee then overturned the original decision and awarded the penalty to Aston Villa.
