You forgot a world class goal keeper in that list.
Good of Le Grove to finally name his "names". Both undoubtedly world class talent though and would be highly welcomed. I think Reus is simply impossible - he's too well coveted and we don't represent enough of a step up from Dortumund for him to specifically choose us ahead of a Barca or Real.
Sanchez is a possibility but if he keeps putting in the world class performances he has been during the world cup Barca may just change his mind and keep him. They're batshit insane in the first place to let him go (assuming it's all true).
Either way we need to actually deliver on something. Another seasons of trying but succeeding simply won't be acceptable. Move hard, fastand decisively and if you can't get your target look for something as close to it. E.g. - If Sanchez/Reus fails we need to be all over Greizzeman in a flash.
