Why the fuck shouldn't they? Barcelona, Real Madrid, the scum and Bayern have tapped up and bought players for years. They realised other clubs had the money to compete so decided to try and protect themselves via FFP. PSG are just doing what they've done previously. If you've got the money and want to spend it to improve why not, you sometimes need to spend short term to accumulate long term. We spent money building an academy that will help keep the current stability and sustainability.
