Critics claim that analysis like XG are ruining the game by reducing it to complex metrics. On the other hand, supporters insist that luck and variance play a significant role in unexpected events on the field rather than in any type of mystical influence.

Although the debate between statistics and purists on the fact that XG should be used in football has decreased in recent years, one thing is indisputable: if you want to be a better bettor, understand data and learn how it can be useful – and misleading – is essential.

Complete disclaimer: this is not just another guide to explanation XG. Those exist on the Internetincluded right here TO Atletico. Instead, we created a piece for bettors who want to refine their skills before putting their next bet. So, let’s start things with a suitable conversation appetizer: American baseball (no, really).

Your dream of being Billy Beane is dead

In 2003, Michael Lewis wrote one of the most influential sports books of all time: “Moneyball: the art of winning an unjust game”. For those who refuse to entertain Baseball or Brad Pitt films, Lewis describes in detail as under the general manager Billy Beane, The Oakland Athletic’s-A team financially challenged that tries to compete with deep rivals-used the analysis to remodel the competitive scene of sport.

An example that contributed to the successes of the A was their recognition that the basic percentage (OBP) counted much more than the average. Beane moved away from the traditional emphasis on the capacity to hit (measured by the average in the beat) and instead concentrated on the acquisition of players who excelled to climb on the base (measured by OBP).

As ruthless as American baseball, the way this rudimentary statistics has provided such a competitive advantage in the early 2000s is absurd. What would be equally extravagant is to think that you can now use XG in the same way to beat the bookmakers when betting in the Premier League.

Unless you were among the handfuls of XG enthusiasts in the early 2010 years lurking in the distant corners of the internet and on the blog on a new way of analyzing football, you probably bet in an era when the bookmakers use that metric much better than you.

Just betting on a club by investigating their total xgs underlying or against one in an unsustainable way they are overcome their competitive advantage. The bookmakers models are better than yours, Billy, so don’t believe that in working with XG in 2025, you discovered something revolutionary like Oops in 2003.

So what is the best way to use XG in the sphere of betting? To begin with, it is important to understand how it could deceive you.

“Lies, damn lies and statistics!”

Mark Twain probably had no knowledge of the impact that the position of a defender has when a blow was taken on a football field, but his words serve to remember that becoming excessively obsessed with XG is not always a wise idea. Like any statistics, the XG numbers do not reveal universal truths: they are simply a tool that needs a context to be useful. The more you understand the context, the more likely it is that you will be able to discover the value.

One of the places that XG can often deceive is in the results of the individual games, since its predictive power is rooted in the aggregate. Give a respectable XG model 10, 20 or 30 and remains one of the most predictive sports metrics. Take too much from a single game, however, and often it can hurt more than well.

In a single game, the minor moments that tend to standardize the long-term-uno-term back pass that went badly or a clear and a possibility that produces a punctual possibility-it distorts the total xg. For example, take the total of 1.67 xg of Bournemouth against Manchester City in that of last weekend FA CUP Quarter-Final.

If cherries can create almost two goals of possibilities against a team of Pep Guardiola grouped, they should not have problems against the city of Ipswich in 18th place in their next appointment. Considering Bournemouth’s poor defense against citizens, the over 3.5 goals for Wednesday clash at the Vitality Stadium with the 7/5 probability seem even more appetizing.

Yet immersed deeper in that total of 1.67 xg and you will find an evident red flag. Almost the entire total cherry XG came from two shots from the same sequence in the 21st minute of the game. Outside of these two possibilities, Bournemouth has created a miserable XG of 0.22.

Do you still feel good for the one for bet?

The Goldocks principle

If letting the games accumulate to ensure more predictive power from XG favors the models of the bookmakers and individual results are too misleading, there has remained only one place to use XG to inform your bets.

Small sections in the games where a significant change occurred seem to be the weak point.

Whether it’s a new manager, an end-of-season injury or a new formation, introducing variables to status-tooth can also cancel the best models and offer a more profitable betting value.

The best place to let XG Guidi is the series of results after one of those events remodel one side, like a key lesion. We use a hypothetical with one of the best non -attackers of the League: Bruno Guimarães of Newcastle.

Newcastle Square against Brentford this week as favorites to win with probability of ¾. With a team completely fit, there may not be much value in taking that bet. But if their stellar midfielder Guimarães had recently lost several games and Magpies XG numbers had simultaneously a dip, Thomas Frank’s men weighed a attractive choice of 17/5.

Guimarães does not cost much in Newcastle as regards the metrics to score. The Brazilian International is in sixth place for the club in the statistics of XG + XA (scheduled assist) for 90 minutes, just in front of the midfielder Joe Willock. Bookmakers can change the chances of Gazze in the absence of their wounded talisman, Alexander Isak, but do not expect seismic changes in the markets for anyone else.

Most of the Guimarães value lies in his disappearance. The 27 -year -old leads the quality passage championship with an evaluation of 96.3 out of 100, for classification scale of PFF players FC. Since the link between the progression of the ball and the creation of randomness is still in some way a mystery for many in world football, there are also random sports books.

This is the perfect recipe for the “weak point XG”. Bookmakers do not radically adapt the probability of Newcastle after a handful of games with mediocre results. Yet players like Guimarães have a remarkable impact on how a team produces and contains possibilities that come out for specific periods of time.

Go to the XG trend too early and you may not be able to capitalize on a payment. Go too late and the bookmakers will eat your lunch. Find the right balance, however, and it could be a good way to improve your betting strategy.
