Ruben Dias should have received a second yellow card and been sent off in Manchester City's game against Nottingham Forest just after Christmas, the PGMO have admitted.

PGMO officials accepted that Dias's challenge on Igor Jesus, 18 seconds into the second half, was worthy of a yellow card. Dias had already been booked in the first half for dissent.

However, the rules state that the VAR cannot intervene in cases of yellow cards, and the referees body was clear in explaining that it was a subjective call by the on-field referee.

Forest complained to the referees body following City's 2-1 victory and requested an explanation. Sky Sports News has been told that club representatives met with officials from PGMO on Monday to analyse the decision not to send City's vice-captain off, and a number of other contentious calls from referee Rob Jones and the other officials in the match.

However, in turn, Forest have accepted that City's winner in that match, when Rayan Cherki scored, was a legitimate goal - despite manager Sean Dyche being very animated post-match, saying that the goal should have been ruled out because he felt that Morgan Gibbs-White was fouled immediately before Cherki's strike.
