None of this is true. Football has spawned a huge internet business for nerds in recent times but the game is not mathematics, and will always be art over science. If a team is constantly unlucky, they are not good enough. When we have played teams like Spurs historically, and they have played better but everyone expects us to win the game, which we do - what is the stat for that? Were Spurs ‘expected to win’ because of their mathematics? Or were United expected to win because of who they are?
When there are title races and teams pull out a ‘performance of Champions’ by digging in and winning late, how many times do they need to do that before it is not luck? And why did everyone deep down know that the other team probably wasn’t going to win? Why has there been a saying ‘not to write United off’ in games for decades? Or why do people predict Real Madrid to win in the CL despite how they have played? I’ve watched countless City games during their dominance where they have looked like they could drop points, but deep down, everyone expects them to win. To sit at a computer and say a team didn’t deserve to be champions because they went on a winning run where they ground out results is nonsensical, for example.
Xg is a load of nonsense, which should have been clear from the beginning when the conversation was constantly about how someone ‘outperformed’ or ‘underperformed’ their xG. And even if we are going to play this xG game - what was the xG of these ‘20 shots a game’ we faced all season? We finished 8th over 38 games because that’s what we deserved. We could have even finished higher, we didn’t exactly make a late surge to finish 8th. It was more the other way around, we were fighting for a CL spot a few weeks earlier. To say that we actually deserved to finish 15th because a calculator said so is ludicrous.
Watch football matches, and decide for yourself.
It's funny you call stats "internet business for nerds", as if football clubs aren't analysing data and have analytics departments. Maybe you should tell professional football clubs to sack their analytics and data staff as they're a waste of money?
Firstly, I never used the word "deserved".
If your argument is the team who scores the most goals in any given game are deserved winners, irrespective of who had the most chances or better chances - fair enough, that's a completely reasonable position to hold.
The points you're ignoring is, the more chances you create over a season, and the less chances you allow the opposition to have, the more likely you are to finish higher in the table. So teams and fans have a very vested interest in how many chances your team is creating and how many they're conceding, because it's going to have a huge impact on where your team finishes in the table.
The 2 pieces to being a successful football team
1. Consistently create more chances and better chances than your opposition
2. Consistently be more clinical in finishing the goalscoring chances than your opposition
If you do not consider the first point to be important, this is why you finish 8th one season, 15th the next - because your performances are consistently shite - one season you'll finish higher because you're more clinical than the opposition, the next season you'll finish lower because the variance when it comes finishing is not in your favour this time.
If you want to be consistently finishing top 4 as a minimum, season after season, you cannot have xG and xGA figures of a lower half team. That's just common sense.
Secondly, I do watch our football matches, and I thought we performed mostly at the standard of a lower half team, given the amount of chances the opposition had, and the amount of chances we had. That was what anyone's eyes would have told them if they watched our games. The xG statistics just happen to reflect what our eyes were telling us.
