Earning more than the yearly budget

This is an interesting story of how one club thinks how to make a pure profit in a years to come, and besides that is thinking of his rivals from the championship too. Probably the high-quality youth academy is the Ajax football school, who have set a perfect example for others and is showing why is the best in the world.
In 2015 Ajax have purchased Frenkie de Jong from Willem II for only 1 euro. Throughout the years this youngster had grown up into a promising player where every team was in the race to have him. It seems that Barcelona was the quickest, when eight days ago offered 75 million euros plus 11 million on bonuses. Together with this agreement, now the 21-year-old midfielder, has helped his first club as well. Besides from that 1 euro, Willem II is having high expectations from this move: 10 percent of the next transfer, or translated - 6.4 million euros. And this amount for the team from Tilburg is higher than their yearly budget.
