Lacazette, Sanchez and Ozil, finally playing together in a big game, demonstrated a link-up that was enough to rival the front three of any top team. Nevermind Barcelona's MSN or Real Madrid's BBC, Arsenal's LSO took the headlines this weekend. And what an apt acronym it is.
Arsenal's London Symphony Orchestra took to the field and played with the eloquence and grace of a Mozart symphony, passing the ball with ease, leaving Spurs gawping. By contrast, Tottenham's attack was stagnant, easily dealt with by the confident Gunners defence.
This victory was not owed to a tactical masterclass from Wenger, or a drastic change in any department. It was down to motivation. Ozil, a player renowned for a lack of effort, was the man of the match, and Sanchez responded to cynics, who believed he had stopped trying before an inevitable transfer, by sealing the victory with a creative finish. The hype of a north London Derby inspired a low-energy Emirates Stadium, creating an atmosphere that has been lacking in recent games, and the players lapped it up.
But is this the turning point? It is easy to become over-confident after the positive adrenaline this derby provided, and I would not be surprised if Arsenal went on and lost to Burnley next week.
But this could be the moment that inspires the rest of the season. A comparatively restful Christmas break and a rejuvenated fan base bodes well for the future and, for the first time ever, fans are not expecting a trophy, but simply Champions’ League qualification.
This season has the potential for being the first in many years from which fans come out satisfied.
There is no better way of turning over this new leaf than with a victory over Spurs. It feels good.
