I am not English so I do not care what they did in 1990. Portugal finished third in their group so in a proper tournament they go home after 3 matches. Then they had a really easy run to the final and still were not impressive.
You don't care but the same media has 2 different points of view about each team's performances, but anyway...
It is true that Portugal finished third, as in other tournaments when the WC was 24 teams other teams who were third made an good knockout stage and I do not remeber anyone saying lack of competetiveness, like Belgium in 1986, Argentina in 1990, Italy in 1994, those are rules and Portugal played by the rules, what is the problem?
Regarding the group stage it is true there were 3 draws, but in none of these matches, maybe only in the final minutes of the last match Portugal played to draw.
What happened is simple and at the same time longer to explain and probably will happen and happened in the past even if only now some media or fans see the problem started with Portugal.
First match we started playing in a sort of 4/4/2 diamond against Iceland because Fernando Santos rightly so understood that as we only had Eder as an striker it would be pointless to start playing in 4/3/3, in the first half we were better, in the second half Iceland was better, fair result, none of the teams played to draw, even if in Portugal point of view there were problems with the defensive line and midfield.
Second match, Santos changed the system to 4/3/3, put William in the place of Danilo and an front 3 of Quaresma, Nani and Ronaldo, we probably played our best match of the tournament, outplayed Austria, hit 2 balls in the post, and missed 1 penalty, should have won that match by 2 or 3 and in the end it was an draw, fair enough, it never happened in the story of Euros and WC, only the bad Portuguese team made this, pesky lucky bastards.
Third match against Hungary, return to 4/4/2 and lots of problems in midfield and defensive line, Hungary were 3 times ahead and final result was 3:3, awfull match, lots of defensive mistakes in my point of view, and the analysis here and in the media was cracking match, probably by the same ones who say that an certain league is the best in the world, go figure, maybe coaching and tactics are not needed.
To simplify this I only say if Santos did not had the right perception and did not made radical changes in the starting eleven against Croacia not only we would lose, but we would lose heavily if we played like in the group stage, the defensive line changed to Cedric/Fonte/Pepe/Guerreiro, and the midfield changed to 3 players from Sporting and Sanches from Benfica, and in that match in my opinion at an defensive level we were perfect and we shut down Modric and Rakitic, while the other teams didn't.
The rest is history, I will only say to you that we certainly were not the best, we had better squads in the past who were in semifinals and one final in the Euro and they didn't won, we were/are in an transitional phase, we brought to the competition Cedric and Danilo who were finalists in the under 20 WC in 2011, William, Guerreiro, Joao Mário, André Gomes from the team who was finalist in the Under 21 Euros in 2015, and Sanches who only had experience in an under 17 Euros in 2014, and we had also bad luck with Bernardo Silva injury before the tournament, hopefully Santos will start using him instead of Nani or Quaresma.
Certainly in my point of view the best team was France, they had better squad but lost, it never happened this in the Euros and WC playing better and losing, only this time probably, the second one was Germany, who has not only great individual players but also works with the same coach since 2004, even if Klinsmann was there between 2004 and 2006, and an football history who speaks for itself, and Italy who had by long distance the best coach of the tournament, the rest was balanced, it was hard against Croatia and Poland, the games were hard for us and for them.
As I said in a lot of posts, my 5 favourites for Russia are: 1- France 2 - Brasil 3 - Germany 4 - Argentina 5 - Italy, so you see no Portugal here, no delusion or arrogance, my only doubt is if I switch Spain for Argentina if Bauza does not change.
Enjoy.
