"If you're going to play in these tournaments then it's even better to be from Iceland and do it, because it's so special", added Saevarsson.
Argentina's preparations for the tournament ended with a frustrating hiccup when a friendly against Israel was cancelled for political reasons, leaving Sampaoli and company heading into a potentially testing encounter against Iceland having played just one friendly game against Haiti since losing to Spain back in March.
Aguero will start up front for Argentina after Sampaoli confirmed his side's starting XI for the game against Iceland during his pre-match press conference.
Argentina boasts an incredibly strong attacking force, with Lionel Messi, Aguero, Higuain, Dybala and Angel Di Maria among the world-class talent in the squad.
Argentina have also topped their group in each of the last three World Cups.
Iceland have failed to win in their last four matches, which would usually give a team cause for concern. They have also won their opening game in each of the last six editions.
Their passage to Russian Federation followed a famous Euro 2016 campaign, where they humiliated England on the way to the quarter-finals.
Iceland may be the smallest country ever to qualify for a World Cup, but Sampaoli was not underestimating his opponents.
Argentina coach Jorge Sampoali needs to ensure his more fancied charges are kept on their toes to avoid a World Cup shock.
There has been talk of this being 30-year-old Messi's last World Cup, but Sampaoli does not believe that places him under any further pressure.
During that process, Iceland put together seven victories across 10 games in order to edge beyond Croatia into the only automatic qualification berth in the group. They ended with losses in two quarterfinals and the 2014 final, all against Germany. 2014 Golden Ball victor Lionel Messi is 9/4 favourite to open the scoring, with Gonzalo Higuain and Sergio Aguero both at 3/1 to break the deadlock.
