This time it's different when RVP left there was still a sense of things getting better back then. Couple players being able to command far more money with the fact the club has no real ambition and you've got recipe for disaster. Not to mention the message it sends to fellow world class players.
If either of Özil or Sanchez or perhaps both leave then what? Which world class player worth their salt will come here? Can't even say for money because not only are we seemingly not competing with the other top clubs in that respect but they can match us with ease, no need to talk about wining anything significant because they know they'll win sweet FA here.
The days of taking players surplus from Real, Barca and the like will be over IMO and we'll be left with mediocrity. And even if we were to attempt to develop stars we're getting beaten to the elite talent in Europe to the likes of Dortmund and Monaco which says it all.
Considering the climate now either or both of them leaving will have a far adverse effect than that of RVP that's for sure.
