I don't hate the model if I am honest. Not sure how I would feel if we were on the Grasshoppers end of this sort of relationship, but from the selfish point of view of a Wolves fan I have no issue with the buying and parking of talent there as a sort of development school.
If you are spending 4-6 million on these sorts of transfers a year then you only need one of them roughly ever 3 seasons to work out for the Wolves first team, for it to have been worth it relatively. I get there are other costs (wages, coaches infrastructure etc) however still I understand the model and why its attractive.
