Understanding Football Stats: xG, Possession & More Explained

Open any modern match page and you are met with a wall of numbers: xG, possession percentages, shots on target, corners, fouls and cards. These statistics can turn a bare scoreline into a detailed story - but only if you know what they mean. This explainer breaks down the most common football stats in plain language so you can read a match at a glance.

Expected Goals (xG)

Expected goals, usually written as xG, is the stat that has changed how fans talk about football. It measures the quality of the chances a team creates. Every shot is assigned a value between 0 and 1 based on how likely a goal was from that position - factors like distance, angle and whether it was a header or a clear one-on-one.

A tap-in from two yards might be worth 0.9 xG, while a speculative effort from thirty yards might be 0.03. Add up all a team's chances and you get their total xG for the match. If a side has 2.5 xG but scored only once, they created enough good chances to expect more goals - they were either wasteful or unlucky.

xG does not tell you who won. It tells you who deserved to, based on the chances created.

Possession

Possession is the percentage of the match a team spent in control of the ball. A 65-35 split means one side held the ball for roughly two-thirds of the game. It is one of the most quoted stats, but also one of the most misunderstood.

High possession does not guarantee success. Some teams deliberately sit deep, concede the ball and strike on the counter-attack. Possession is most useful when read alongside other numbers - lots of possession with few shots suggests sterile, ineffective control, while high possession backed by high xG shows genuine dominance.

Shots and Shots on Target

Total shots count every attempt at goal; shots on target count only those that would have gone in without a save or block. The gap between the two is revealing.

• Many shots, few on target - a team is shooting from poor positions or lacks composure.
• Few shots, most on target - a side is patient and picks its moments.
• High shots on target, low score - credit the opposing goalkeeper.

Corners, Fouls and Cards

Corners often reflect sustained pressure, since they usually come from attacks that force a defensive clearance. A high corner count hints at a team camped in the opposition half, though corners themselves convert to goals fairly rarely.

Fouls and cards describe the temperature of a match. A game with twenty-plus fouls is likely scrappy and physical. Yellow and red cards matter even more: a red card forces a team to play a man short, which reshapes the entire contest and often shows up immediately in the possession and xG figures.

How to Read a Stats Line

The skill is not memorising individual numbers but reading them together. Try this quick method:

• Start with xG versus goals - did the scoreline match the chances?
• Check possession against shots - was control turned into threat?
• Look for a card - a red often explains an odd-looking stat line.
• Compare shots on target - this is the clearest measure of who tested the keeper.

Read this way, a stats panel becomes a summary of the match you may not have seen. A team that lost 1-0 but posted 2.3 xG, 60 percent possession and eight shots on target was desperately unlucky - and next time, the numbers suggest, the result may go their way.
