One sure way to know that soccer season is starting again after the Summer pause is:
1) you have more reports on TV and radio about "new" players
2) players changing teams
3) trainers commenting and boasting about the goals they want to reach this year
4) fans of soccer teams excitedly hoist the team flags and dress in team colors
5 ) But also when you drive with your local train and see all the mess the fans left behind when going with it to the stadium for a first (friendly) match. So obvious after 6 weeks of clean trains.
Not happy about it at all. :-((
