can get into trouble trying to keep up. Leeds United attempted to do this by spending a lot of money and were successful for a few seasons. However, the debts became unmanageable, the successful players were sold off and the team were eventually relegated twice, first from the Premier League to the Championship, and then to League One. Not all clubs do well out of television money. Clubs in lower leagues receive less money for matches and, if promoted to higher leagues, can have trouble matching the spending power of bigger clubs. This leaves them more likely to be relegated again. Clubs from smaller countries also have problems with this issue. Due to their smaller population base they receive less money from television rights. This means they are comparative paupers compared to clubs from the bigger countries, and can lead to debt problems if they try to match spending in trans-national competitions. Some clubs have managed to buck the trend by training players through their youth academies, as well as making wise investments. Examples of these clubs include Porto and Ajax, although when these teams become successful, as in Porto's case winning the 2003–04 UEFA Champions League, the players tend to get sold-off due to financial pressures. In 2021, Newcastle United became the richest football club in the world after being bought-out by the Saudi Arabian government's sovereign wealth fund. Society In many countries, football has ingrained itself into the national culture, and many parts of life revolve around it. While incarcerated in Robben Island prison, Nelson Mandela reflected on how playing football "made us feel alive and triumphant despite the situation we found ourselves in". Many countries have daily football newspapers, as well as football magazines. The mood of regions and countries has been seen to be connected to football, especially during major tournaments where victory can bring happiness to the local community or country. Conversely defeat can lower spirits, and has been seen to be connected to mortality in the population. Withdrawal symptoms when the football season finished have also been reported. The economy can also be seen to be connected to major football tournaments, although the precise association is disputed. The terms "soccer mom" and "soccer dad", popularised in the United States, refer broadly to a demographic group of parents with school-age children playing football.
