I've not really got a problem with the self sufficient approach to be honest. It's better than splurging on players who are only really coming because we overpay on wages compared to clubs of a similar profile.
If a players is available and they thinks it's good value they'll pay it, but they aren't going to pay over the odds in wages as compensation for coming to a what's seen as a lesser team. It'd be pretty easy to hit the limits of FFP by having a big squad full of overpaid mercenaries we can't shift because no other club would pay their inflated wages.
I do think they are committed long term in terms of growing the club, they've just decided (rightly or wrongly) that to throw money at it probably isn't the wisest approach. If they weren't commited long term, it wouldn't really make sense to me that they are still buying players on potential with a view to their value increasing years down the line.
The other aspect is I don't know if I'd feel fully comfortable in them just throwing money at it and loading the club with debt, if they ever did then truly lose interest, that could become quite messy, especially if most of the playing squad were overpaid.
I'm still overall quite positive, some of the players we have now are just incredible compared to a few years ago. We've got a squad full of international players who've won titles in Spain, France and Portugal. I'm looking forward to the next few years in seeing how all these 'wonderkids' like Neto, Ait Nouri, Trincao and Silva develop as well, and I'm sure there will be more to come too.
So that post turned into quite a long one but in summary yes I think they are commited. Of course that's all just a guess from me and they could be looking to sell ASAP, I just think they're in it for the long haul.
