You are assuming that Portugal had the team to play their attacking football, they don't have Figo, Sousa, Rui Costa anymore. Queiroz did the best he could get away with that team, and even played a good game against Spain and Brazil, there was a part of the game from the min 20 till 55 against Spain that Portugal even played well, minus CR.
Queiroz lacks the respect of some players and some commentators, like Mourinho once upon a time, he used to be called The Translator of Bobby Robson, until Mou got some results. If Queiroz had won this game against Spain the story would be similar.
Sports science has evolved a lot in the last decades, and finally this world cup is showing us that being a former player doesn't give you what it's needed to be a good coach, it goes way beyond that, there was even some breakthroughs on Math due to the investigation done on Barcelona FC.
My point is, Queiroz is the best man for the place atm, maybe someone more charismatic like Mou would get the people appraisal, but going for names like Manuel José would be making several steps backwards.
