FC's Stewart Robson and Alexis Nunes look ahead to Denmark-Australia, France-Peru, Argentina-Croatia and predict who'll come out on top.
Another adverse outcome on Thursday and many may even start to consider the unthinkable - that Argentina could be on their way out at the group stage, mirroring their shock first round exit in 2002. Argentina, on the other hand, did not disappoint all that much in the attacking side of the game and it was largely down to the resilience of Iceland that they could not score more goals from open play.
"All our friends are now in Moscow and we have booked places to stay here for the first two weeks, so we will go to Nizhny and Saint Petersburg on the day of the games and return immediately after", said Leonardo, who has travelled from Buenos Aires and will stay for the whole tournament. We have nothing to lose. "Not only is he the best player in the world on the pitch, he is also best player off the field".
The Reds defender helped his home nation beat Nigeria 2-0 in their opening game of the tournament in Russian Federation and is in confident mood ahead of the clash.
Messi had a penalty saved in Argentina's 1-1 draw with Iceland on Saturday, one day after Cristiano Ronaldo had a hat trick in Portugal's 3-3 draw with Spain.
Now they meet Croatia in their second Group D game, and the Vatreni will prove to be a tricky opposition.
But Croatia has fabulous individuals on their team, too, specifically the midfield pairing of Rakitic and Real Madrid's Luka Modric.
Liverpool centre-back Dejan Lovren is relishing the chance to face Lionel Messi when Croatia take on Argentina at the World Cup this evening. "The most important thing is to stop him, but it will be hard", the midfielder said. Rakitic said. "The world knows". He will have his moments, clearly.
"We have to play a ideal match to win", he admitted.
"It's a handsome thing to play against one of the best teams in the world. We are especially motivated". That result means that Argentina must win this game or they will be at risk to not make it out of the group.
