I heard that Juventus is going to be relegated. What is going on and what is relegation?

Competitions at all levels are like a pyramid. The top players at the lower level can enter the higher-level league, and the lower-level players at the higher level will be dropped into the lower-level league. The league is generally held once a year. That is to say, if Juventus is relegated to Serie C. Only if they perform well next year can they enter Serie B, and then can they return to Serie A if they perform well in another year. Some older players may not be able to stand playing in low-level leagues and transfer. In this way Juventus may not be able to enter Serie A for many years. The downgrade of several top clubs will lower the level of the Serie A, further leading to the loss of high-level players from other clubs. The decline in viewing pleasure will also lead to the loss of viewers, and broadcast revenue will also drop. This vicious cycle will affect Italian football. It will be huge
