Claudius Striker markets have always been tough, very few top class ones around so even the ones who aren't top top tier or top prospects go for stupid money.
Jhon Duran is averaging a goal every 90mins I think in this league, the money is crazy but if clubs cough it up they'll have seen the guy and watched him carefully in this league for 3 seasons now so will have a good idea if he'll step up or not. I think around £60m would have been fair for him in this market but Saudi's paying stupid money for their project
I think @Sicario touched on it earlier, Fergie signed RvP basically to win them the title. Different circumstances as Fergie was about to retire so desperately wanted that last title. Maybe Arteta thinks Watkins can be the one to get us over that phycological barrier and win us the title? Even if it is a waste of resources and we might have to bin him in a few years. I don't know I'm just throwing that out there.
