Thing is, I agree with you, but at the same time I think we'd be stupid to miss out on Ronnie, if he's available for a reasonable price. I think the problem is that we've wasted our galactico quota (ie in my mind, the number of established star players you would accept in the team) on Ballack and Sheva, so the thought of bringing in another one does seem wrong.
However, if you took away those two players, and told me Ronnie was coming in, I'd be ecstatic, as you do sometimes need to spend a bit to get the absolute best in the business, and he is exactly that. We may find our own wonderkid given time, but we sure as hell ain't there yet.
I guess when I see Ronnie in our team, I don't see Sheva or Ballack alongside him, so although that doesn't get away from the fact that we have mistakenly invested in these two players, I don't see us as having a 1st 11 at least of big name galacticos.
Still not convinced either way to be honest, but I just know that if Ronnie is available on the cheap and he ends up at L*verpool or Man U, we will be kicking ourselves.
