When you talk about "administration" in British football, it means that there are problems with the team's money. So they need help from a special group of people called "administrators" to help sort out the team's finances. These people are like helpers who try to make sure the team still has enough money to pay its bills and keep going.
Sometimes, this happens when a team spends too much money on players they can't afford, or maybe they have debt that they can't pay back. The administrators try to figure out how much money the team owes and to who. They also try to find ways to save money and get more money for the team.
Sometimes, when a team is in administration, they might get points taken away in the league. This is because they are not following the rules around money in football. It's important for teams to be careful with their money so they can stay in business and keep playing for their fans.
