The one cause for hope in all this I see is that Newcastle might have a bottomless pit of money now, but they are still Newcastle...I mean, geographically they cant make themselves 'not Newcastle'.
Players can be offered loads of cash and promises of trophies...and that's a big draw for the bulk of players....but the elite, the type of players City and Chelsea and PSG and other nouveaux riche clubs have bagged, have lifestyle in mind as well. The North East of England isn't a draw for those type of players. It's the wilderness. They might snag the odd superstar in the twilight of their careers looking to get a kings ransom for their pension fund for a season or two's work, but they wont get top players at their peak.
