💪”We’re not here just to make up the numbers”Gudni Bergsson tells us Iceland mean business at the #WorldCup 👏 https://t.co/HVhNThMbQN | #TSWorldCup pic.twitter.com/id5DyRI69B— Weekend Breakfast (@talkSPORTWSB) June 16, 2018Key playersArgentina: The Albiceleste shouldnt be so dependent on Lionel Messi, given they boast arguably the best attacking line-up at the tournament, and yet they are. He was the only Argentine to score in their last six South American qualifiers, and even then he only netted in two of them. Thats genuinely difficult to believe given this is a squad which contains Gonzalo Higuain, Sergio Aguero, Paulo Dybala and Angel Di Maria. There is absolutely no chance they would have even qualified without the little magician. But this works both ways. Messi knows he must win a World Cup if he is to be considered the best in the history of the game and needs his team-mates to play up to their reputation.Iceland: Gylfi Sigurdsson has been a key player for Iceland in their recent rise, and he top scored in World Cup qualifying with four goals in 10 matches. His set-piece ability makes Sigurdsson a major attacking outlet for Iceland, as no one else in Hallgrimssons squad provides real quality in the final third. This is why Iceland were panicked when Sigurdsson picked up an injury in March, playing for Everton in the Premier League. He had to see a specialist due to a knee problem which kept him out of action for the remainder of the domestic season, but he was named in Hallgrimssons squad regardless, and returned to training ahead of the tournament.Predicted line-upsArgentina: Caballero: Salvio, Otamendi, Rojo, Tagliafico; Mascherano, Biglia; Meza, Messi, Di Maria; AgueroIceland: Halldorsson; Saevarsson, Arnason, R.
