Ilkay Gundogan's last-minute penalty sealed the points to extend City's winning run to nine matches.
Despite plenty of confusion from many of those watching, Rodri took advantage of a rule which says that an attacking player is played onside at the point a defender intentionally plays the ball. I don't think anyone in this stadium thought it was a goal.
In Juventus's 2-0 win in the Italian Supercup, Ronaldo was coming back an offside position when Napoli's Giovanni Di Lorenzo cut out a Juve pass - Ronaldo flicked the ball away from him and the officials immediately flagged CR7 for interfering with play.
During the protest that led to his dismissal, Smith revealed he was shown a yellow card by referee Jon Moss for bizarrely asking fourth official David Coote "if he got juggling balls for Christmas".
"It wasn't swear words".
The visitors complained that the first goal should not have stood, however, as City midfielder Rodri came from an offside position to steal the ball from centre-back Tyrone Mings after a header from Silva.
"I thought they'd at least go over to the screen because it looked a clear offside when I looked myself".
"It has been a long time since I have scored", Silva said to BT Sport. He came over and said I'm interpreting the laws of the game, and I said you should've done that earlier in the game.
"I think I got treated rather unfairly". I've heard a lot of worse things said to Jonathan Moss before and he's not dealt with it like that.
Until Silva's goal, Villa had acquitted themselves well on their first team's first outing since New Year's Day following a Covid-19 outbreak at the club.
