We’re all pundits these days when it comes to the beautiful game. We think we know it all. Who’ll be getting the cards, who will be scoring a goal and of course, which way a tie will go?
It’s why we back an acca every weekend!
However, there are tools to help and Expected Goals (xG) is one of the best out there for helping punters betting on football earn a tidy profit.
It’s a technological dream that makes playing a number of betting markets that little bit easier.
But how? We hear you cry. Below you’ll find our full guide to Expected Goals and exactly how it works.
What Are Expected Goals?
Expected Goals is a fantastic tool that uses analysis to help predict the number of goals scored in a game.
Often referred to as xG, the metric uses an expansive range of data to make a prediction for the number of goals each team scores.
It’s a fantastic aid for betting and takes out plenty of hard work punters face when making their selections.
The metric itself is produced by Opta, perhaps the most famous football statisticians on earth, so you really do know you’re on to a winner.
How Do Expected Goals Work?
As you’d expect, the way Expected Goals are predicted isn’t built on a hunch, it uses a large set of data and an incredibly sophisticated algorithm. We’d expect nothing less from Opta.
They go into the depths of their own award-winning data, analysing thousands of matches, tens of thousands of shots and goals scored in order to make these predictions.
Every detail is covered, exploring how the shot was taken, how it was assisted and the players involved as well as distances, angles and many more pieces of data.
This is then converted into the expected number of goals a team will score.
This is given as a decimal number due to the complexity of the algorithm, so it’s always worth rounding to the nearest whole in order to get a simpler prediction. Therefore a team with an expected score of 0.72, for example, are more likely to score one goal than zero.
So, let’s say you wanted to bet on a game between Newcastle and West Ham. The Expected Goals data may be suggesting that Newcastle are expected to score 0.84 goals and West Ham 1.67.
In this instance, West Ham would have the edge according to the metric, with Newcastle expected to score one and West Ham just about scraping two goals. Here’s how Sky sometimes display the data –
What Markets Can Expected Goals Help?
Expected Goals is well worth taking note of as it can really help punters in a number of markets.
The scientific algorithm Opta provide is incredibly useful for providing accurate predictions and there are a number of takeaways from it.
Match Result Market
Firstly, it can be a good metric to try and determine the Match Result market as the difference in Goals Expected from each team will generally give you a good idea of who is favourite to win.
In the example above, from the Expected Goals, it’s quite clear that West Ham would be favoured in this particular instance as they are predicted to score two compared to Newcastle’s one.
In theory, the Expected Goals metric should be able to help you forecast the correct score as ultimately it’s predicted how many goals both sides will score.
Newcastle would fall 2-1 in our example, but it can even be a useful metric in predicting score or no-score draws.
Obviously, goals markets are the best markets to play with the xG metric.
There are a number of ways you can do this, playing markets such as BTTS is a popular choice, while it’ll also be useful in predicting total goals whether that be a specific team or a combined total.
The Over/Under market is also worth considering using Expected Goals. For example, if two sides had Expected Goals of 2.12 and 2.40, it may be worth placing a bet on over 3.5 or 4 goals.
Goals Expected Important Information
Naturally, it’s not quite as straightforward as backing a market purely on Expected Goals. It certainly won’t put you in profit every time.
After all, this is football and absolutely anything can happen. A game could see an early red card that changes the entire complexity of a game. The same could apply with an injury, or quite simply a manager may set out not to score their usual goal tally but be a little more cautious.
There are so many variables. However, that doesn’t mean you should shy away from using it. It can aid your betting significantly, it just shouldn’t be the only thing you factor in.
Which Betting App To Play With Using Expected Goals
As Expected Goals is an outside tool, it doesn’t really matter which betting app or market you play, you can use it as your aid.
There are dozens of fantastic betting apps for football out there, across both Android and iOS devices. The likes of Paddy Power, Coral and bet365 all have large football markets to enjoy, meaning you really can make the most of this brilliant tool.
