Point is, as I have made in another thread yesterday, we buy in these guys from abroad, we spend God knows how much on them, we invest time and effort (and it's all cumulative - that's the point !), and then they're a) sold (witness Panathanaikos last night; Leicester; other clubs throughout the leagues); b) loaned out, most likely never to return; or c) released.
What's the point in wasting money on child prodigies who add nothing tangible, not are likely to get the opportunity ?
