They seem to be including the purchase options/obligations for some of their players currently out on loan in the calculations. Here's the breakdown (note: the fees exclude add-ons to calculate a guaranteed total return)
- Sales
- Emerson Royal: €25m
- Junior Firpo: €15m
- Jean-Clair Todibo: €8.5m
- Carles Aleña: €5m
- Rey Manaj: €2.7m
- Loans + purchase options/obligations
- Francisco Trincão: £25m (~€29.14m)
- Antoine Griezmann: €40m
- Total: €125.34
It's ~€5m less than the €130m claimed in the Tweet, but it's not that far away, either.
