Another wild weekend in the Premier League saw Arsenal's failings on and off the field laid bare, Liverpool's title credentials enhanced yet again and Leicester show they're the real deal after scoring nine at Southampton. We get you caught up on the action with the Weekend Review.

Is this the end of Emery and Xhaka?

The margins are fine in football. Unai Emery was one abysmal VAR decision (on which, more later) from a second win in a row, a hard-fought and restorative three points to follow the win against Vitoria Guimaraes in the Europa League, after the horribly limp loss to Sheffield United last Monday. It's also easy to forget that Arsenal didn't actually lose to Crystal Palace.

But Sunday's 2-2 draw felt like the day something snapped among the Arsenal fans, of course not helped by Granit Xhaka. Everyone realises that being booed by your own supporters is unpleasant, humiliating and in an ideal world wouldn't happen at all. But Xhaka's reaction was absurd, immature and self-defeating.

It's not so much the cupped ear or the expletives as he stalked off down the tunnel that are objectionable. Those could be understandable, if not really excusable. But deliberately slowing down as he walked off, when his team had let a two-goal lead slip and were chasing the game, was unforgivable and suggested he was more concerned with making a petty point against some people who were being mean to him, than his own team winning.

- Emery: Dropping Ozil backed by club

- Xhaka tantrum not most shocking thing in this picture

This comes back to Emery, too. He did, after all, appoint Xhaka as the first of his five captains, the fifth of whom was Mesut Ozil, now ostracised from the first team.

More tangible than who he chooses for a ceremonial role are results. Arsenal have won two of their past eight, and stretching back to the dreadful end of last season which cost them a Champions League spot, they have won six of their past 17 and taken 23 points from an available 51.

Which would just about be acceptable if there was any sense of a style coming through, of progress being made, a new identity forged. But there's none of that. It wouldn't be a surprise if Emery is dismissed in the next couple of weeks.

VAR: worse than anyone imagined

It's pretty remarkable just how much of a mess the Premier League have managed to make of VAR. It was bad -- really bad -- before this weekend, but now it's gone completely haywire. After some of the decisions overturned this weekend, the "high bar" we were told that would be applied has now been lowered to shoelace level: it feels a bit like a restaurant dress code suddenly changing from white tie and tails to Speedos and slippers.

Over the games this weekend we've seen Everton, heading for victory against Brighton, penalised because Michael Keane might have trodden on Aaron Connolly's foot; Norwich concede a spot kick against Manchester United that even Ole Gunnar Solskjaer didn't think was a penalty; and Arsenal lose out on three points when Calum Chambers was seemingly punished for being fouled.

It almost feels like VAR is a truculent child, who after being told it wasn't changing enough decisions, suddenly just said: "Well, let's see how you like THIS."

As it's being applied at the moment, VAR has turned English football into a chaotic farce, impossible to have any faith in, virtually unwatchable because this malevolent cloud is hanging over everything.

The stated aim at the start of the season was for VAR to improve the ratio of correct refereeing decisions from 82% to 95%. The question then was whether the potential disruption would be worth the extra 13%, but now not only does that figure feel like ludicrous optimism, we're going the other way.

Liverpool's mentality monsters do it again
