Argentina, who have won the World Cup twice, have taken just three points in their last four games. A win would guarantee Argentina at least fifth place but a draw might be enough to take them into the top four depending on results elsewhere. Brazil have qualified already and Uruguay are almost certain to join them. Colombia, Peru, Paraguay, Argentina and Chile are all fighting for the remaining spots. Sampaoli, who took over in June and has yet to record a competitive win, has not named his side for the match but Lionel Messi is sure to start. "If we are up to Messi's standards in tomorrow's game then we'll be alright," Sampaoli said. Argentina have beaten Ecuador only once in a World Cup qualifier in Quito, where the high altitude makes life difficult for visiting teams.It's judgement day for Messi & Argentina!
