Alejandro Sabella's Argentina will look to keep up their winning start to this year's World Cup and face Switzerland on Tuesday with the prospect of making it four from four in Brazil.
Lionel Messi's individual brilliance bailed La Albiceleste out of trouble on more than one occasion during the group stages, and Sabella will once again be looking to his talismanic forward for inspiration against the Swiss.
Ottmar Hitzfeld, meanwhile, faces an uphill battle in holding the South Americans back, but his underdog outfit will nonetheless take to the Arena de Sao Paulo with the aim of putting on a stubborn display. All viewing information and a detailed preview is ahead.

Should they advance from the round of 16, Argentina can hope to see Sergio Aguero line up in their quarter-final tie, but it's asking too much of the Manchester City man to shrug off a thigh strain in time for Tuesday's outing.
Aguero's injury was confirmed by ESPN FC over the weekend:
Having already come on as a substitute for his teammate at this World Cup, Paris Saint-Germain is the most logical choice to replace Aguero in the starting XI, but Rodrigo Palacio offers another avenue for Sabella.
Broadcaster Paul Sarahs argues that the striker's absence may yet work in the South Americans' favour, a theory with which WhoScored.com's Martin Laurence concurs:
Switzerland will undoubtedly be happy to see their opponents' attacking reserves reduced somewhat, but Hitzfeld still faces an incredible struggle in extending his side's campaign.
Having failed to do so in previous tournaments, Lionel Messi is finally summoning his optimum powers at a World Cup, and what better time to do so than in the backyard of your nation's most bitter rivals?
As things stand, the forward is one behind leading Colombia's James Rodriguez in the top scorer ranks, but the prospect of facing a Swiss defence that conceded five goals against Les Bleus will assuredly give Messi something to be cheerful about.
ESPN's Miguel Delaney quotes coach Sabella in giving his assessment of the Barcelona star, while Squawka illustrates just how directly his dribbling has influenced matters:
Having scored in each of La Albiceleste's three group fixtures, Messi has another task in attempting to put his team through to a quarter-final where they will face either Belgium or the United States.
