Hi! I'm Victor, one of the researchers behind this project. We used the most recent lineups (up to yesterday) to do the predictions you see on the web page. We will update them with the latest friendlies (e.g., Portugal indeed) and before every game, as soon as we have the official lineups!

It may be worth taking competitive matches into account over friendly matches, as the purpose of competitive matches is to win at all cost. Friendly matches, on the other hand, tend to be used primarily for match fitness (especially leading up to tournaments), and for trialling new tactics before the competitive games begin.

Thanks for the clarification and great project!

It will be interesting to see how things change when you get the official lineups. As I'm sure you are aware, teams often rest their 'star' players in friendlies immediately prior to a tournament in order to minimize the risk of injury.
