Here's the brilliant Alan Alger's with his must-read column on Arsenal's stirring triumph at Luton as well as victory over Wolves as a tough trip to Aston Villa looms this weekend 

Narrow margins still in our favour…

The victories over Wolves and Luton were our sixth and seventh one-goal margin wins of the season. That’s over 60% of our successes in the league coming by the narrowest of measures.

On Saturday we had to dig deep at the end when the referee (rightly) played eight minutes of injury time when we were holding on. Last night it was the Luton Town fans chance to feel aggrieved as the referee again correctly played additional minutes for time wasted within the added-on. The new directive has helped the bigger teams find winning goals towards the end of matches and is a rare welcome addition to the way games are officiated.

We have scored in minutes 93, 96, 101, 96 again and 97 already this season. Fighting all the way to the end for a net difference of 6 points, a similar gap at which we lead the early table.

That’s the kind of impact that time can make. We also seem more grounded as a team this season and I have every faith that the battling to the end won’t just apply to minutes of the game, but months of the season.

Arteta unfairly targeted by both questions and officials…

He was asked “have you spoken to Raya?”. Mikel Arteta responded with “I love my team”. That exchange came after an embarrassing and unusual question from their correspondent at Kenilworth Road last night. It seems only our boss has to face such direct interrogation about things which reporters tend to shy away from asking other managers in the league. It wasn’t exactly the perfect answer from Mikel when put on the spot, but it gave the right message.

This occurred only minutes after our Spanish gaffer had unfairly been booked for celebrating a last minute winner in which maybe one of his toes crossed the boundary of his technical area.

Again I definitely feel this doesn’t happen to anyone else in his position. He now has to take on board a position in the stands at Aston Villa on Saturday, a ban that every referee seems to have been gunning for since the summer.

Defensive frailties hidden by the stats…

We find ourselves in a strange position defensively, the judgement on goals conceded has us comfortably at the right end of the table, yet we also top the table for errors leading to goals.

In one way we have a superb and well organised defence that is difficult to breach - in another we have a calamitous collective that make more errors than anyone else. If ever there was a more confusing set of stats to get your head around?

We have a defence that look extremely well marshalled and tough to break down in normal play, yet the trip to Luton saw us concede two agricultural style goals from corners where we looked all at sea. Luton scored three goals as we restricted them to just 0.63 of xG- the kind of numbers that place heavy questions on goalkeeping.

We won’t go there, again, but those numbers do suggest we’ve got the process right and we continue to give up no more than scraps in each league encounter. It’s just that Luton were better at feeding off them.

We have to hope that Villa’s more clinical players do not get a sniff at the weekend and that we defend our set plays perfectly.

In the circumstances and considering our incredible run of form, I think I’d shake hands on a point now.

The fixtures get trickier and maintaining this unbeaten run for as long as possible has to be the objective.
