Pep Guardiola said Juan Cancelo's red card worth it because he fouled the last man and still said that it would be a lesson to other players. Since it's the last man, he should be left to go, the keeper may save it and if the keeper didn't save it, they would remain the eleven Players on the field and hope to score goals and there is still time, it's not last minutes but it's not all players that understands this. Juan Cancelo is the reason why Manchester City didn't have as many as possible goals that they used to have in each matches because they have shot one already and it's one of the midfielders that would move to defense line to cover Juan Cancelo's place.
The penalty taken for Kelvin De-bruyne is what people are still taking about now, they said the penalty is too soft, the way that he was fouled isn't the way that he fell down, he added dive to it and Premier league has already said that they won't blow for any minor kick this season, so as it's premier league, it's not enough to be taken as penalty. There is contact in it but as its taken as penalty, then premier league referee didn't abide with the rule that they aim to play with in this season.
The same thing Juan Cancelo did to collect red card happened when Tottenham Hotspur played against Liverpool at Tottenham Hotspur home, where Alexander-Arnold and sessegnon, where Sessegnon pushed Alexander-Anold inside box 18 just like the way Juan Cancelo pushed opponent inside box 18 but it wasn't taken as penalty. Premier league referees are the ones that dismantles the laws themselves, they use different rules for different matches but the thing is left for the players, don't because they said they won't blow minimal fowls and started fighting Kung Fu on the pitch or playing as if you are playing Shaolin soccer ⚽.
The only fair referee now is Micheal Oliver and it's not that he's so good like the Spanish referees but he is fair more than other Premier league referees, if Micheal Oliver is the one that officiate a match, I know that there won't be too much mistake. To avoid mistake is the reason why VAR exist but those that are in charge of the Premier league VAR might be the one to cause another World War because what they take is always rubbish but it's still the referee's fault because referee have the chance to check it out himself by seeing the pitch side monitor before he make decision.
