Yep. Its unsustainable because we are not big enough or not able to generate enough income to be self sustaining as a top 5 club. That's the harsh reality.
That's because its not possible. If you have a group of players who are good enough to get you into the top 6, then guess what they'll want pay packets that are the same as at the other top clubs, otherwise they'll be off.
Football's all about money, simple as that. We don't have any so unless we get a shiekh in a la man city then we have to accept that we are going to be a feeder team for the bigger clubs, we can at best finish about 6th in the league and maybe we might get a FA cup or carling cup win sometime. That's it. We are not able to compete for CL or a league title.
