Isakly what we need

Aye I'm in the same boat but with Wissa rather than Mateta.
I think Wissa would fit in well. He is a super finisher and has great movement that would suit our game. But, given his age, I would not want to pay too much and I think Brentford are unlikely to let him go.
 
Isak will undoubtedly tear us a new one when we play them away in the second fixture of the new season. It’s written.
He will have a back injury & miss the fixture - he doesn't want to jeopardise the proposed swap deal with Ektititktktk next summer
 
I was going to ask exactly this, then saw you had, and then realised @MomoWASright hadn't responded.

@MomoWASright, I think you may be misunderstanding the metric.
The metric should be he scores 19/20. To say he should only be scoring 16 of those is kind of arbitrary. He’s just fucking good at them based on real data. In a hypothetical game, it’s drab, zero chances for either side, Milner gets a pen. What is the xG? 0.8 - 0.00 or 0.95 - 0.00? Looking at the real data, it’s 0.95.

xG utilises, I think, 5 metrics. Where on the pitch the ball is, distance, angle (could really be rolled into the first), shot or header and defensive set up. Like I said in the post, there are way too many variables. Like with the pen, is the chances of scoring a pen 80% in the 84th minute whether 7-0 up or at 0-0 in the 38th game of the season to win you the league? Is it away? Which supporters are you shooting towards? What are the weather and pitch conditions? It applies the same scoring when all things are not equal.

xG tries to over simplify what is a technical thing.
 
The xG metric for a penalty is always the same though. Doesn’t matter who takes it.
Milner being good at them doesn’t make them a bigger chance for the stat pages.

So, you're suggesting that it actually needs to take in more metrics to be more accurate? Maybe it does, but at least it's not as simple as all chances are equal. There's probably trade offs with adding in things that are more subjective.

But, it absolutely needs to be taken into consideration with other things, it shouldnt be used in isolation, it's just a better metric than chance conversion as it attempts to put in the difficulty.

This I agree with. It shouldn’t be the be all and end all. Over the years it has been given too much prominence. Saying how did city lose 2-1 when they won xG 4.85 to 0.55 when if you were to look at the actual game you’d get better answers through other metrics.

Yeah, but you could be pretty sure that they were pretty shit in front of goal, it wasn't a lack of creating good chances, it was not putting them away. Maybe something else too.

All that stuff should be washed out if you have a big enough dataset.

I don't really understand your stance on the Milner thing. An average pen taker would score 80% based on the stats. Milner being way better than average has no bearing on that, surely?

If every shot in each zone of the pitch was roughly equal then yes, but there are too many variables including a shit load of luck.

Presenting a Milner penalty as 80% is wrong because we have a better source of data to help make a more complete reflection on what happened.
 
Ekitike was the one striker we were linked to I didn't want. I'm a hopeless optimist so the xg thing doesn't bother me that much, but you'd be a fool to argue it's not a concern.

I just don't think he looks very good.

Anyway, genuinely hope I'm completely wrong.
I'm 100% in that boat. Really really hope I'm a terrible judge of potential.

Oh I see what you're getting at - ie that it'd be wrong to say we had 0.8xG when really it was 0.95 in our particular case, etc?

I think that sort of shortcoming is just inherent in the metric isn't it? It's not saying these chances will convert to x goals for this team, but as an average across all teams. It's not really there to make an actual prediction - it's not meant to be intelligent in that way. It's basically just a chance creation measurement. And then how tightly chances created will correlate with goals will vary by team based on different factors which xG isn't designed to assess.

Except in the case when Arsenal xG is better than PSG - then it clearly and, indisputably, demonstrates that Arsenal are the best team in Europe, but conversely, second only to Chelsea in the world.
