Football in Poland is everywhere. Polish kids start kicking a ball around the moment they can walk. The most famous Polish footballer today is Robert Lewandowski, a striker known around the world for scoring lots of goals. Children try to copy his moves in the playground.
Volleyball might be even more loved than football right now. The Polish men's national team has won the world championship, and when they play big matches the whole country watches. People hang flags out of their windows. Schools set up TVs in the hall. Kids practise serves over a net stretched across the playground.
What is special about both sports is that you cannot win them alone. In volleyball, the ball is supposed to be touched three times by three different players before it goes back over the net. So you must trust the people around you. A team that plays selfishly never wins.
Polish schools have lots of inter-school football and volleyball matches. Some children play on village teams, some in city clubs. Even kids who don't play in a team usually have a 'kick about' after school. The same six-year-old who can't tie their shoelaces yet can sometimes score an amazing goal with their friends.
