  • Expected goals is a football metric that measures the quality of chances created, used to estimate how many goals a team 'should' have scored.
  • No.

What models do

A model uses data to estimate the probability of outcomes, which you can compare with the odds to look for value. It is a tool for forming your own view.

Common approaches

In football, the Poisson distribution is often used to estimate goal counts, and 'expected goals' (xG) measures chance quality.

Example. A model might estimate a team's chance of winning from past data, which you compare with the implied probability of the odds.

Limits of models

Models are simplifications. They miss context like injuries, motivation and conditions, and past data does not guarantee future results. They inform judgement, not replace it.

Using them sensibly

Treat a model as one input alongside knowledge and discipline. It supports value betting but is not a crystal ball. Always bet within a budget.
