What are xG, xA and xGI expected stats?

Used a lot in modern football analysis, what exactly are the xG, xA and xGI expected stats? Knowing this can aid Fantasy Premier League (FPL) managers.

After years of counting basic events like possession and goal attempts, the last decade or so has brought a demand for some context-based statistics that can more accurately measure good and bad.
xG – Expected goals
This is a way of measuring the quality of shots, rather than quantity.
It calculates the probability that a shot will be scored, compared to many previous ones with similar characteristics.
Each individual attempt comes between 0 and 1, where the distance from goal naturally plays a big part, but it’s also based on other factors, like the angle, the body part and other players being nearby. On a simpler level, penalties are rated at 0.79, due to their 79% conversion rate.

For example, in 2024/25, Evanilson bagged 10 league goals, but he accumulated a higher xG of 12.46. It can be concluded that the striker was sometimes missing some ‘easy’ chances.
xA – Expected assists
Similarly, this calculates the likelihood that a completed pass will lead to its recipient scoring.
Another occasion where each is between 0 and 1, factors include player location, pass type, pass distance and its end point.

In 2024/25, Phil Foden ended with two league assists, but racked up a higher xA of 5.34. Unlike before, this is fairly critical of teammates, rather than the midfielder doing badly.
xGI – Expected goal involvement
Meanwhile, this is the straightforward addition of xG and xA.
In a match, if a player’s three attempts add up to 1.12 xG and they also set up 0.64 xA of chances for others, that day’s xGI is 1.76.
For instance, Mohamed Salah had a phenomenal 2024/25 of 29 goals and 18 assists. But his xG (25.37) and xA (9.06) combined for a 34.43 xGI tally, the league’s highest.
How FPL managers use these numbers

In FPL, having your team collect the highest-scoring players is a reaction. A good one, too.
But to achieve true greatness, a manager needs to also try predicting the next must-have asset. Studying xG and xGI data for underachievers and overachievers is one way of approaching this.
Although it’s not always true that these numbers eventually balance themselves out – as seen in the earlier examples – there’s usually some faith that a lucky or unlucky player’s points are about to change.
