Croatia have failed to advance past the group stage since their debut as an independent country at the 1998 World Cup in France, where they finished third.
Argentina eventually took command and delivered wave after wave of attacks in the second half but they actually created few clear chances either side of the poorly-struck 64th-minute penalty by Messi, who had a remarkable 11 shots during the match.
We've all heard the statistics: everyone from Iceland except Björk and Sigur Ros are at the tournament, their population is roughly the size of your front room, all their players were playing Sunday League until they got the call to go to the World Cup.
Maradona, who played against Super Eagles at Nigeria's debut at the Mundial in 1994 in US, told Argentine Television Telesur's "De la mano del Diez" show that the way his country played in the opening game of Group D against Iceland leaves much to be desired.
"It was a hard match against an excellent opponent".
"Leo showed he's human".
Labelled as the best Croatian squad since the 1998 group, they will once again need to deal with lofty expectations.
Defender Javier Mascherano added: "We have to move on".
"It is right that expectations are high and we expect from ourselves more than anybody else". It's a very competitive group.
"Obviously it hurts me to have missed the penalty".
"I hope it is going to prove important to us to reach our goal to qualify", Halldorsson said of the penalty save.
Speaking with TyC Sports, Crespo who represented at three FIFA World Cups (1998, 2002, 2006), said: "As a coach, I like him and he makes me enthusiastic".
Winger Rebic agreed with the assessment of his team-mate, saying: "Against Argentina we have to be united, Messi is 50 percent of the team, if we defend ... all together, we have a great chance". "I guess our game plan worked nearly perfectly".
