From the Emirates. It's nice to have an unprovable theory. It's easy to insist that England would've won Euro 2004 if Wayne Rooney hadn't got injured (which, by the way, they definitely would). If Abou Diaby hadn't had his injuries, he would've won a Ballon d'Or. If Santi Cazorla hadn't missed most of the 2015/16 season, Arsenal would've beaten Leicester to the title.
It's brilliant. You get to have a thing you believe, you can talk about it till the cows come home, and nobody can ever – for definite – say 'no, that's not true, look'.
The flip side of that coin, of course, if the provable theory. Because that can very quickly become a disprovable theory, and then a disproved one, and then you have to admit that you were wrong. And admitting you're wrong sucks.
A lot of Arsenal fans have been running with a dangerously provable theory in the last few weeks. Everything would be better if Arsenal just made a couple of changes, see, and if Arteta used the squad properly. And when's Mohamed Elneny being given a run in midfield?!
Tuesday night's strong-but-rotated lineup against a decent Leeds side meant that a handful of those fringe players (all of whom appear to have had their reputations vastly improved by not being given the chance to do anything wrong) got a chance to earn themselves a Premier League starting spot.
