Here to defend two minutes of injury-time after seven substitution and five goals at the City, plus much more, is a former premier league ref.
Although the result was already far beyond doubt, eyebrows were raised in the Manchester City ranks when only two additional minutes were signaled by the fourth official at the end of the Manchester derby.
It was unusual to have two minutes added on at the end of the Manchester derby. There were three or four minutes added on in the first and second half. The Manchester derby was very unusual because of the amount of time added on.
He looked at the rest of the talking points.

Gabriel Martinelli was caught on the side of the ankle by the studs of Emerson Royal as he tried to challenge him. He was shown a red card by Anthony Taylor.
The decision was correct, according to De Reverend's verdict.
When you see the assistant's view, it's obvious that this is what they've worked on all season and I thought it was going to be.
Dermot says: "It's got better, it's got quicker. It's a work in progress, it's the third year in this country - and it's better than it was two years ago. There's the movement now to get dedicated VARs, Mike Dean and Lee Mason, they're there every week, and entrusted.
"Referees are now going in, they're circulating, learning about it. It's never going to be perfect, people will always agree on decisions. That's what happens, we see things differently. You've got to judge the whole package, not just one decision."
The challenge directly above the ankle has been seen this season. I don't think the referee was justified in sending off van Dijk in the derby.

The last man, Thiago Silva, is caught in possession of Jordan Ayew in the middle of the field. He lost his balance in the challenge and ended up on the floor, where he slaps the ball away from the Palace forward.
Palace chairman Steve Parish was upset that he wasn't sent off because he was shown a yellow card.
The decision was correct, according to De Reverend's verdict.
"I think it's a yellow card and the referee has the right to do that," DeRM OT said. I think it's a chance to score a goal. He needs to get the ball and move towards the goal. Can he get there before the defender? Sending him off is obvious.
A red herring was thrown to me saying there were two yellow cards, but only one was given, so that killed the other.

There is a free kick in the penalty area. After a brief review, the referee waves away the incident.
It would have been easy to give.
It's a huge risk to do that, why you would do that? If the referee is sent over to the review monitor by the VAR, they might recommend a penalty.
I don't think he's going to argue about it.
Luis Sinisterra was shown a second yellow card three minutes after the break for sticking his leg out to block a free-kick.
The decision was correct, according to De Reverend's verdict.
The referee should be given the opportunity, according to De Reverend. You're asking them to make a decision because you're on a yellow card. The only thing he can do is a yellow card.
He paid a heavy price for being sent off on the halfway line. He gave the ref no choice.

Sean Longstaff was caught on the side of the shin by a sliding challenge. After VAR Mike Dean sent him over to the review monitor, he changed the booking to a red card.
The decision was correct, according to De Reverend's verdict.
"I think it's a good idea from Mike Dean to show him the film." He went with studs above the ankle and when he saw it again, it was a red card.

Jordan was knocked off his feet by a challenge from the other team's player. The referee sent the calls for a penalty to the VAR review screen, where he stood by his original decision.
The decision was wrong according to demot's verdict.
I thought it was a penalty. Ajer gets the ball after the man, and when he slides in, Zemura jumps in. I think it's a penalty because if you're sliding in for the ball you don't have to raise your leg.
I don't know if Tom is thinking about the fact that Ajer has the ball. He will eventually get it. He might not have known that he had gone through the player.
