In citeh's case I can't see how they won't be successful at least in the short term, but hopefuly the new rulings will put constraints on the way they run the club, limiting them again to rely on core fan base long term, which will be ultimately unsustainable.
'pool are in a mess, and to a lesser extent so are man u, but there is much to be said about their global following and how long term they will always bounce back, unfortunately...the major loser from the top 4 will be chelski in my opinion, for as strong as their squad seems now there is evidence to suggest that they can no longer rely on the sugar daddy's money, and with an aging squad, unreliable global profile and smallish stadium, times are changing for them, thank God.
So where does that leave us? Strong, as ever, really...the new rules could just coincide with the emergence of some of the best crop of youngsters ever to come through the club, and this seems to be on going for the next few seasons...we can already witness Wilshere showing quality of being a real star, add Theo, Ramsey, Gibbs etc to this then, again, even short term we have an impressive bunch to add to the more "grown up" contingent of Denilson, Diaby, Nasri Nik etc, who may or may not prove to be successful. However, I think it's the slightly younger crop that will prove to be "the ones" ultimately: Afobe, Aneke, Lansbury, Silva added to the forementioned JW, Gibbs, Theo and we have a great squad set for a decade...and we can't forget that we are a massive "brand" with a sizeable fan base and traditional profile. We're pretty sexy, in short.
Just need a 'keeper, defence coach, dm...same old story I know, but if we're speaking of sustainable business models for the next decade+ I'm glad that ours looks so achievable compared to our rivals both here and in Europe. Patience.
