If you take our squad, add those three to it, and add on top of that a half decent RB and another CM just for fun, do you think we are as good as any of the teams that figure to finish top 4 that aren't Leicester? For me Carlo or not in the dugout, we're still easily behind them. So imo, not enough.
My feeling is we do it the hard way or we don't do it at all. I can't see a plausible scenario where we establish ourselves as a top notch club without building up to it or Usmanov bankrolling us City style. Or I guess the other clubs making a Super League and us not being invited.
