Maybe they didn't realise they'd get this good this quickly and that their worth will have increased?
It's an interesting one, because the club can justifiably say that it's probably no coincidence that a bunch of our squad just so happen to be playing the best football of their careers all at the same time. We can for sure be confident it's the environment we've given them to flourish that's enabled them to do that.
Ok the other hand, if I'm one of the best in the world in my position and another team is not only promising to double my money but make me a starter, why am I staying?
Even at the end of last season, you could probably argue that a bunch of our talents needed to prove they could consistently be top level before top clubs would give them key roles, but now those players have proven it again - there's no surprise that other clubs will be demonstrating serious interest. In an ideal world they would all hold on until there's a genuine starting space at a Real, Barca or Bayern, and if not just stick with what they have. Skip the Emirates Marketing Project route and these guys could be earning the real mega bucks if they do for us what Bale did.
