Koen Kampioen wants to score

Koen reads an intense message in the newspaper. His football club Stark is in trouble and almost bankrupt! Koen and his teammates start looking for sponsors, but that doesn't really make any progress. In fact, he doesn't have time for it at all. Koen is so busy with football that his grades at school are declining. As a result, he is no longer allowed to train, even though he is currently in a form crisis! Things are not going well in Koen's group of friends either. How should Koen solve all these problems? And will he manage to keep his starting places at Stark and in the Orange Under 15 team?
