Diego Maradona fired a warning to Argentina coach Jorge Sampaoli after the two-time champions drew their opening match of the 2018 World Cup against debutants Iceland. The Albiceleste were held to a 1-1 draw, the first real upset of the showpiece event this year. Sergio Aguero gave the two-time world champions the lead after 19 minutes before Iceland, showing the same commitment and self-belief that saw them stun the soccer world with their run to the Euro 2016 quarter-finals, hit back four minutes later through Alfred Finnbogason.
Argentina, playing in all-black and roared on by the vast majority of the crowd in a rocking Spartak Stadium, eventually took command, delivering wave after wave of attacks in the second half.
