A group in which all sides have a chance of going through.

After losing to Germany in the previous World Cup it all went downhill for the Argentinian national team. Messi retired, and the qualification was not going as planned, but things turned around and Messi returned to rescue his nation and accomplished his task by scoring a hattrick in the final qualifier. Argentina have only managed to play one friendly before the World Cup which they won. They have a great squad and their forwards are the jewels in the team. Argentina in all likelihood will make it past the group stage and the quarter finals should be their minimum expectation.
Iceland make their first appearance in a World Cup, they do this after having impressed at Euro 2016 and gaining praise universally.

Iceland make their first appearance in a World Cup and having exceeded expectations in Euro 2016 they are in group which can help them replicate those performances. Iceland played two friendlies losing one and drawing the other. Reaching the World Cup is already a great achievement for the nation, and with the exception of Argentina they can easily challenge for the second place spot. Expectations are that Iceland will fall short of second place but could finish a respectable third in tough group.
Croatia have played in four World Cups till now their first coming in 1998 in which they also finished third in the competition.

Manager – Zlatko Dalic
Most Caps – Luka Modrić (106)
Captain – Luka Modrić
Star Player – Luka Modrić
Croatia are favourites to qualify from the group along with Argentina, they always ply beautiful football and are at times unlucky to not make it further in competitions. Croatia played two friendlies to prepare for the summer, losing one and winning the other. With some brilliant players in the squad and Modrić pulling the strings Croatia should make it past the group stage and could make it up to the quarter finals. A favourable draw could only see them go farther.
Nigeria have participated in five World Cups, having reached the round of 16 in 94, 98, and 2014. Their first World Cup came in 1994.
Goalkeepers – Ikechukwu Ezenwa (Enyimba), Daniel Akpeyi (Chippa United), Francis Uzoho (Deportivo La Coruna)
Defenders – Brian Idowu (Amkar Perm), Elderson Echiéjilé (Cercle Brugge), William Troost-Ekong (Bursaspor), Leon Balogun (Mainz 05), Shehu Abdullahi (Bursaspor), Chidozie Awaziem (Nantes), Tyronne Ebuehi (ADO Den Haag), Kenneth Omeruo (Kasimpasa)

Manager – Gernot Rohr
Most Caps – John Obi Mikel (85)
Captain – John Obi Mikel
Star Player – John Obi Mikel
Whether they do well in the World Cup depends on the Nigerian team but they have already won best kit of the competition. Nigeria have some star players in the squad especially in their midfield and forward lines. John Obi Mikel provides the experience and strength at the centre of all movements forward with players like Moses, Iwobi, and Musa providing the attacking threat. Nigeria could make it to the round of 16 but anything more would be a bonus and their best performance in a World Cup.
