Apparently all their current loans are with a view to permanant deals (they're supposed to be tying up deals for a few this month I believe).
Tbh I thought the same as you about Mendes having read up his dodgy dealings at Valencia, but talking to my Wolves mate and doing a little digging, their owners and Mendes are basically in business together. I doubt he'd want to piss off the very people he's in business with by rinsing them for a quick buck. Think the use of an agent for this particular club is unique in that it's not purely Mendes wanting a quick buck, both work together. Ngl I'm a tad envious, they have the world's most powerful agent on their doorstep, purchasing bright talent from abroad for them with resale value. Meanwhile, we're stuck with potato head who signs his mates and old fogies with no long term strategy whatsoever.
