You can use that argument with every single player. Until the management and philosophy of the club changes, we'll win nothing. And it's true, we can sell any player at the club, and that won't change.
Personally, I think it'd be better if we can hand on to the next manager and owner with as many tools at their disposal as possible to actually win something. Robin's part of that, I hope, so would Cesc have been and Nasri too even. There's the alternate, destructive view, that the lower we go now the better chance we have that the kind of change we need actually comes about sooner. I absolutely understand that, but it's an odd argument to make for anyone who puts such over-importance on Champions League qualification and the third place trophy.
Reality is, Robin has been more important to us than I can think of any player in any other league. And that includes Ronaldo and Messi. We have been by far, by an absolute mile more dependent on him than any other player in this league has been important to their team this season. We can sell, (maybe) replace and move on. But I don't see how anyone can envisage a scenario where we're a stronger squad or it.
