Sweden v Portugal (0-1 agg) - Friends Arena, Solna (Swe) - 19:45 GMT
Portugal have a narrow lead over Sweden going into tonight's fixture thanks to a headed goal by Cristiano Ronaldo in the first-leg.
Both country's star men Ronaldo and Ibrahimovic are desperate to secure their places at next years World Cup and will be doing everything they can to ensure it - promising a thrilling match.
The match is being officiated by English referee Howard Webb, with both camps seemingly happy with this appointment.
Swedish midfielder Sebastian Larsson told the Swedish media: "We have an English referee now so we can probably go in a bit harder.
"I do not think he is going to fall for the same tricks so easily.
"Howard Webb is used to refereeing where the game is a little more physical. He's a great referee, too, which is important for such a big game."
Cristiano Ronaldo won a number of free kicks in the first leg and was the likely target of Larsson's comments, however earlier this year Ronaldo himself praised Webb and the Ballon d'Or contender is expecting 'another battle'.
He said: "Portugal have a small advantage, and we are expecting a very difficult game, but we are ready.
"We will have to be fully focused. More than anything else, these players want to be in Brazil, so we will give our best to get there."
The match is likely to be played in conditions of near freezing temperature, which will suit the Swedish players in their bid to overcome the one goal deficit.
Home side Sweden have no new injury concerns as goalkeeper Andreas Isaksson was passed after suffering a knock in the first leg, with manager Erik Hamren expected to name the same side he fielded in Lisbon.
For Portugal, Real Madrid duo Ronaldo and Pepe sat out training on Saturday, but that was just precautionary and both players will start for the favourites.
