The one thing that Newcastle have not bargained for is expectations.
We have fans who assume that we will battle with City every years because we have in the past, the better you do the more people expect of you.
I think many fans assume Newcastle are a Champions League club now. They qualified narrowly because Liverpool, Chelsea and Spurs were poor last year Next year all 3 of thise will be better and Brighton and Villa will be sniffing around as well. Newcastle have not improved to the degree they can establish themselves as a top 4 team and break the grip of the top 6 clubs, especially as they have CL football to deal with as well.
It will be interesting to see how their value as a club is if they finish 7th next year, if they don't make progress I suspect they will struggle to justify some of their marketing value. City managed early on to break in and they used money they did not have to do so. Let's see what Newcastle do to move to where they want (and expect) to be without doing what City did (cheat) to get there.
