Completely agree. So many people just can't or won't see it though. Until we actually do start selling players for big money, we will be seen as 'League 1' by clubs trying to buy our players, and they'll bid accordingly.
It's only now though that we're starting to see the sort of value our key assets could realise. I completely get why we didn't sell White to Leeds for example - as well as needing him this season we'll get far more than £25m if his development continues as it is, and it's only this season that Biss is starting to be talked about amongst the 'top 6'. I don't think its something we're averse to doing, we're just waiting for the right time. Fully expect one of our best players to go for £40-50m in the summer (and providing we've got a replacement lined up it'll be the right thing to do)
