Nah, everyone knows that happened with FDJ and others, but they were being paid massively over the market rate. Apart from FDJ, they were generally hangers on. What you do there is hope they still have some pride to play, and hold the prospect of them not being in the professional squad, or shipped to some uncomfortable place, as your leverage in getting them to take a more reasonable rate.
I mean, lets be honest, there's been no problem paying Lewandoski or Raphina has there? No. Of course not.
Sour grapes are understandable, but not that admirable. And your argument is a swing and a miss. He'll be paid, no doubt about it. Better to send them on their way with best wishes.
