For others? For sure.
For us? Very far from pretty doable.
I don't think he's worth 50 at all but as I said in the post, rumoured. 20 is a good price for George, it's just when you add it to the 50 it becomes a lot, and we're still one of the few teams that have to be PSR compliant.
So, say we get Grealish for 30, 20 for George - 50 from the get-go. We need 2 first team starters (WBs), likely 20-30 each, a backup striker and at least 1 more near-starting quality winger needed, say 20 again. So somewhere between 110-140m to spend. No chance in fresh hell we are allowed to do that or even do that.
Outgoings will be minimal - Patterson, Mykolenko won't fetch high prices, neither will Beto. McNeil I fear Moyes will like for some reason and will want him and also no one wants him too, so it's a hard bargain to recoup any money there too.
Now if we somehow get Europe this season, we'd need at least 3-4 players on top of those mentioned otherwise we'll go backwards in both competitions due to fixture congestion. So we'll need, what, 150-200m to be spent in one summer? Not a chance.
