As some of our more "fragile" posters are worrying about getting " scrollers thumb" on the what our opponents thread, and because we were in fact spamming up the thread if we're honest, I took the advice given and started this fred so we can discuss the merits, or not, of the stats that are now permeating the game more and more.

As the old adage says, there are lies, damn lies and statistics, but I'm of the opinion that stats are a useful tool when used in the right way.

For example, one of the better statistics out there, for me, is the xG stat. I went through the reasons why in the other thread and really can't be arsed to type all that shit out again but, in a nutshell, I believe it provides a fairly accurate measure of how well a team has performed in an attacking sense as well as from a defensive perspective. The Wolves game is a prime example of this, whilst they dominated possession, their xG was less than 1, meaning that they were restricted by a good defensive performance, whilst our xG was nearer 2, showing that we created effectively double the decent scoring opportunities, despite having far less of the ball.

Now the point I made was that the stats should be viewed in conjunction with what you're actually seeing on the pitch, not as something separate. My reasoning behind that is that the two together give a far better understanding of the tactical approach employed. For example, had Wolves xG been up around the 3 mark, that tells me that they have battered us, we've got it badly wrong in our approach and we've only won the game out of sheer luck, bad finishing or a goalkeeper having an absolute worldie. The fact that they were below 1 backs up what I saw when I watched the game, a team set up to control their attacking threat and exploit the space left on the counterattack, creating better chances because that was the plan all along.

I'm not going to claim that xG is infallible because it isn't, the same as any other stat taken in isolation. For example, my Old Man is obsessed by possession stats. If he sees we've dominated possession and lost, he's straight in there with the " how the feck did we lose that game?" mantra, without really thinking about what was actually.done with the ball. For me, the possession stat is the most misleading of the lot when taken in isolation as it doesn't reflect your effectiveness, whether you were penetrative, on the front foot etc. I've lost count of the times we've moaned about how we've passed around in front of an opposition to no effect, then had our pants pulled down and lost the game.

So, whilst stats are marmite to many, maybe that's because they are looking at them from a Black and White perspective rather than as a supplement to what we watch so that we can better understand what was actually happening on the pitch.

Again, I think the Wolves game is a perfect example of this, with many thinking that we nicked the game because Wolves had all the possession. Whereas I saw a tactical setup utilised to exploit their front foot aggression, and the stats back this up.

Discuss ;)

The trouble with stats is that on their own they are often meaningless. They are only useful in a wider context.

For example a player may have massive pass completion stats that in reality were just sideways passes between the centre backs or from a deep lying midfielder back to the defenders.

I've spammed my opinions in the other thread, but to summarise:

I don't dislike stats, but it's football has ramped up it's obsession with them in recent years. I remember watching a Champions League game on BT Sports I think it was maybe two seasons ago, Michael Owen was still on commentary so maybe longer than that? Well, there was a great goal, I think Griezmann scored it, and instead of being excited for the great goal that was scored Michael Owen was screaming about how "HE'S GOT GREAT NUMBERS!!!!!!" - And it just took me out of the moment and made me think "What the fuck has happened to football?"

Some stats are fine, some stats are utter wank. "Dribbles completed" for example. What the fuck constitutes a "completed dribble" - Does a player have to carry the ball a certain distance? Do they have to beat a man whilst doing it? Utter gash.

Assist stats are also misleading. As I have mentioned before, a keeper could pass to a player who beats every single man on the pitch 4 times, smashing the ball into the top corner. Assist for the keeper. Nonsense stuff.

I was trying to have a discussion with someone about Son on Twitter, saying he'd be an even better player if he got his head up and passed to players in better positions. The answer I got was "He's got 7 assists mate. Highest on the team." - There's no consideration from that guy that maybe that's not the full picture. That stat proves everything to him, and it really doesn't. People trying to shoehorn stats to prove a point which would be obvious if they were just watching players for themselves is frustrating. I don't need stats to know that Son needs better decision making at times, I just watch him play.

Expected Goals is fine but it doesn't take into consideration things like that quality of the goalkeeper, or the quality of the player having the shot. Like if a chance falls to Kane there's more chance of it being a goal than if it falls to Sissoko. We could have 5 expected goals, and they all fell to Sissoko, so we lose 1-0 to a team who scored their only expected goal shot.

So yeah. Stats, they're fun aren't they? As if I don't get enough spreadsheets in work.

Where do people get their stats from?

I found this site a while ago: https://understat.com/league/EPL it has xG for all games and even has league table that you can sort by xPTS
It's a good way to quickly see which teams are "over achieving".

I've also got an Android app called Infogol that shows the xG on a map.

Is there a good app or website for heat/influence maps? I find it interesting seeing players/teams average positions, but I can't think of anywhere that shows it.
