All eyes will be on Ronaldo and co as punters can watch Sweden v Portugal live streaming with Bet365, who report thy are televising all the action through their website tonight (KO 19:45GMT).
Portugal find themselves as slight 8/5 favourites as they take a slender 1-0 lead to Stockholm ahead of the second playoff leg against Sweden.
Portugal never make life easy for themselves when it comes to qualifying for a major tournament and they will once again need to be at their best if they are to hold on to their slender advantage against Sweden.
The Portuguese have their superstar Cristiano Ronaldo to thank for the one goal advantage after scoring a late header in the first leg on Friday night.
Ronaldo will once again be leading the line for Portugal at the Friends Arena as he looks to be the focal point of Paulo Bento’s 4-4-2 strategy.
Bento could very well be tempted to field a rather defensive squad for tomorrow night’s game in Stockholm with Miguel Veloso and Raul Meireles likely to be at the heart of the midfield.
Its a a similar position for Portugal’s squad to be in having qualified for the 2010 World Cup in a similar fashion where they eventually disposed of Bosnia with a 5-0 win in the second leg after drawing 0-0 in the first leg in Sarajevo.
Sweden have performed admirably in their last few games putting in some decent performances against top opposition but not quite getting the result they have wanted.
However, manager Erik Hamren will be keen to convert their hard work into a win on Tuesday night and is likely to stick with a similar squad to the one that made the trip to Lisbon on Friday night.
This means that Zlatan Ibrahimovic will be the main attacking threat for Sweden as he looks to translate his scintillating form for PSG onto the international stage.
Alongside that, many of Hamren’s more experienced personnel such as Kim Kallstrom, Johan Elmander and Sebastian Larsson will need to be at their best if they are to help Sweden avoid missing the World Cup for the first time since 1998.
Despite losing their last 2 games, Sweden had been unbeaten in 4 games meaning that Hamren’s side know how to pick up a victory despite recent results not going their way.
Tuesday night’s encounter in Stockholm is likely to be a very tense affair and whichever side scores the first goal could be the one that will be heading to Brazil when the final whistle blows.
