Oh, come on. It's not like anyone's putting up the xG as the catch-all Single Final Big Proof that we were shit and Arsenal were great, overruling a lot of conflicting information. The point, made repeatedly, is that xG, shots, touchmaps (Arsenal had 59 touches in our penalty area, we had 11 in theirs. Tomiyasu, a defensive FB who played half the game, had more than any of our players) and eye-test all tell the same story, which is that they subjected us to very heavy offensive pressure, while we did not produce very much in the way of scoring chances. There are clear limits to what xG tells you about a single game, but when it's this disparate, and the shots are equally disparate, and the touchmap tell the same story, and when it was an obvious feature of the game while it was going on that we struggled to control them when they were in possession around our box (for my part I was worried enough about that that I made a post in the match thread about it during the break), what exactly is the point here? That Arsenal were taking lots of speculative shots while we produced fewer but more high-quality chances? Because we really didn't (and of course, if we did, that would also have showed up in the xG). These were the five finishes with the biggest scoring chance of the game:
1. Nketiah (90) 0.61 (Arsenal's third goal)
2. Nketiah (84) 0.47
3. Nketiah (24) 0.42 (Arsenal's first goal)
4. Ødegaard (2) 0.17
5. Nketiah (64) 0.17
We didn't have a single chance that even reached the 0.10 threshold.
Also, I think you'll find that possession was actually about even after the first half. Which is probably one of the reasons this still felt like a close game, and which also contradicts the notion that this was a game where we were happy to sit back and let them have the ball.
So yeah, it was close and we fought well and we've showed progress and there's no reason to hang our heads over this game. But there just isn't a reasonable way of looking at this game that leads you to something other than Arsenal outperforming us big time when it came to generating offense. We didn't produce much, they produced a lot.
