Portugal coach Paulo Bento shrugged off suggestions his side were favourites for the match, saying his only concern is ensuring they qualify for Brazil next summer.
However, he has faith in his side that they can overcome the Swedes.
``We have the ability, conditions and quality to achieve our goal. Tomorrow we have to get a good result without worrying whether we are favourites or not,'' he told a press conference.
``We have to achieve that goal (World Cup qualifying), saying we are favourites is irrelevant.
``We know what we want to do and also what problems our opponents can cause. We want the best result possible.''
Bento added: ``What is my gut feeling? It's good. I don't go into any game without having a good feeling.
``Both teams failed to get first place in their groups and now we're obliged to be better than Sweden in these two games.''
The former national team midfielder is also more than aware of the threat posed by Ibrahimovic, but has warned his team not to focus all their efforts on just him.
``He's a great player who is also in extraordinary form, with great technical ability, but we must not only worry about individuals,'' he added.
