Portuguese league had pretty much the same relative status in Latas' day as it has now.....somewhat 2nd tier but not to be taken forgranted- Though Mourinho's big mouth & Porto's CL triumph in 03/04 did temporarily raise the profile so to speak for the "now comes"- teams like Porto & Benfica (both having won the CL 2wice each...or so) have always garnered some respect without being feared....
'relative' is de key...I think is only de past 15-20 yrs or so that Portuguese football in general has really become globally respected and I think that respect has filtered down some to the domestic league. 20 yrs ago when Latas went there I'm certain that wasn't the case. Of course I have no empirical data to support this...just an overriding sense based on their accomplishments over that period.
Well 3 out of the 4 Champions league triumphs that came from Portuguese teams happened b4 Latas went to Portugal. -
In terms of the Nat'l team- the furthest they've made it in the W.C. was the semi-final in '66 & '06 (I eh feel like confirmin' that on wikipedia- so correck meh if wrong, but I'm pretty sure that's accurate)- but that's once b4 Latas & once after.....other than that they exited in the 1st round in '02 & I think in Mexico '86 as well....again once b4 Latas & once after.....
I hear you though in the sense that their two most recent golden generations (Figo, Rui Costa, Paolo Couto, etc...) & (Ronaldo, Quaresma, Deco etc...) have had arguably the biggest Portuguese impact on the modern game as we know it, and at the Euro champs competition, they've had their greatest sucess in the last 8 years with a semi & final birth in '00 & '04 respectively...
That's the best empirical evidence I could give yuh without research
So I guess it all depends on how yuh look at it...but with Benfica winning CL titles from way back I want to say that the league has had sparks & potential for sometime now.....in terms of Global respect? that's anyone's guess, but in terms of success- the record speaks for itself.....
