As a language model, I don't have real-time access to the latest news and updates on football matches, including upcoming matches like LOSC Lille vs PSG. However, I can provide general information about football teams and their involvement in matches.
Football is a team sport that involves two teams of eleven players each. Each team has a goalkeeper, defenders, midfielders, and forwards. The objective of the game is to score more goals than the opposing team by using various tactics such as passing, dribbling, shooting, and defending.
In football, there are different types of matches depending on the level of competition and the format of the tournament. For example, in the Premier League, which is one of the most popular football leagues worldwide, there are 20 teams divided into four divisions (known as tiers) based on their geographical location. In the English Premier League, there are 10 teams from England, 4 from Scotland, 3 from Wales, and 3 from Northern Ireland. Similarly, other football leagues around the world may also be organized similarly.
On the other hand, international football tournaments involve national teams representing their respective countries. These tournaments are often held every four years and include groups of teams from different continents. For example, the FIFA World Cup, which is the biggest international football tournament, features 32 teams from around the world. Each match in the tournament consists of two teams playing against each other, with the winner advancing to the next round until the final.
So, to answer your question, the number of teams involved in a football match depends on the type of match and the organization or governing body hosting it.
