We can be absolutely certain that whatever we have spent, is within the FFP boundaries & have no worries on that score. No way would they risk that, at this stage.
What I would be interested to know, is if City have benefitted from the new 'relaxation' of rules which has been brought in to help Berlusconi & Co. UEFA originally said that City would not be allowed any 'relaxation' but the media & that bitter fucking twat at Arsenal, keep claiming we have. City should clarify this & rub their noses in it, if it's not true.
It would also be interesting to have some idea of just how much money City could have spent. Whether we are close to the limit, or whether we could have also bought Pogba for instance. Don't suppose we will find that out in a hurry though.
Hopefully for some years now, we will mainly only need to strengthen 'cheaper' positions, bring through a few kids & sign one 'big' player every few seasons on average. We will need to splash out on gradually replacing/reinforcing Yaya & Fernandinho's positions over the coming years but we should have time now to pick & chose targets.
Eventually DS,VK & Aguero will need to be replaced but again we should be in a comfortable position to find the exact players to do that, in the future, rather than being in a huge hurry. We may be able to actually build a large fund, to be in the bidding should a new Messi come along.
What we must do, is 'freshen up' the attack regularly, even if it's just with kids. That keeps the 'buzz' going & stops things from getting stale.
