I “self-identify” as an Arsenal fan. This goes back years and years, all the way back to, oh, 2010, when I figured out I was an Arsenal fan without ever having made a conscious decision on the matter.

Now that I am a fan of three years standing (albeit one who has never seen Arsenal play, nor been to their stadium) … I now am allowed to expect the worst when big matches are involved.

See, I didn’t sign up for Arsenal when they were doing the Invincibles thing; I picked up with them five years into this trophyless spell/era, which is now up to eight years, and counting.

As a latter-day fan, then, I have developed a strong sense of impending doom, and the sirens are going off right now.

Why?

I have constructed this semi-elaborate scenario in which the turning point to what, for three months, looked like an extremely promising season.

The turning point? When Arsenal gave up the tying goal, to some Everton kid, in the 84th minute, at home. This was Saturday last, and it ended in a 1-1 draw — which meant that what could have been a seven-point Arsenal league in the Premier League was, instead, five.

Three days later, Arsenal, leading their brutal Champions League group on the final day … gave up a second goal to Napoli, in the final minute, losing 2-0, and that meant Arsenal finished second in the group, to Dortmund. Had it finished 1-0, they would have won the group.

Huge swing there. Had they won Group F, they would be paired, come the Champions League draw on Monday, with a second-place team in the round of 16. Among the possibles: Olympiakos, Galatasaray, Zenit Saint Petersburg, Bayer Leverkusen.

Teams Arsenal could beat.

Instead, they get a group winner. They cannot be paired with the team which finished ahead of them (Dortmund), nor with fellow English sides Manchester United and Manchester City, but they will get one of these five:

Bayern Munich, Barcelona, Real Madrid, Paris Saint-Germain, Atletico Madrid.

Those are serious teams. More serious than Arsenal is, even in what has been a good season so far. I suppose they have a chance against PSG or Atletico, but the other three?

And tomorrow? They get a Premier League game at Manchester City, and City has been crushing people at home. I don’t see Arsenal getting a result out of that one. Thinking something like 4-1, actually.

And the league lead will be down to two points, probably, or one more bad game, and we know where this leads – to another year without a trophy, and a desperate final charge to salvage a Champions League berth. That’s how the Gunners roll.

(That 2005 FA Cup … know nothing about it, other than they won.)

So, it all goes back to that sloppy goal conceded to Everton only four minutes after Mesut Ozil had given the Gunners a lead. They couldn’t kill 10 minutes and get out of there with three points. Of course not.

I felt a premonition as it happened. And premonitions among Arsenal fans, even those of three years standing, are always of bad things.
