Transfer fees have been high. Net 250 mil euros since Qataris took over. But you can't really compare PSG to other clubs because they're building a team from scratch... very few players had the level needed from before 2 years ago.

Currently, with the departure of Nene and the arrival of Lucas, PSG has an annual wage of 87.9 million euros. It really is very reasonable. French players' wages are very cheap in comparison to others in Europe. Although the transfer fees have been high, the wages are good. See details of the wages below:
