The days of teams of teams from Portugal or Holland being relevant in Europe are over (I say that while agreeing with Josh that this FCP team can go to the CL semis this year or next). I think the difference between FCP and the mega-money teams is depth. Porto has terrific depth, but teams like ManU or Barca can bring guys off the bench that nobody else can due to their financial advantage.
Italy and even the well run Germans are pretty much there too. The CL has become a competition between 4 English teams and 2 Spanish. I'd say this stinks, but a majority of the global audience seems very happy with this setup. To this day, that '04 FCP winner still gets little to no respect outside Portugal. If they wore Arsenal's uniform, Mourinho would now be knows as Sir Jose.
