The FIFA World Cup 2018 promises to be an exciting tournament, with the likes of Cristiano Ronaldo, Lionel Messi, Neymar and more set to dazzle the watching audience with their incomparable skills.

While individuals will, no doubt, make their mark in this year's tournament, the team that wins the title will be, well, the one that plays like a team, as Germany showed so wonderfully-well four years ago.

One of those "teams" could be from Groups E or F. Here is a look at how the sides in those two groups stack up, along with the entire squads of all the eight counties – four each from the two groups.

Group E:

Brazil, Swizerland, Costa Rica, Serbia:

The Selecao might have been far and away the best team in the South American qualifiers, but, in many ways, they are still trying to move on from that 7-1 pasting they took at the hands of Germany in the 2014 World Cup, and that too on home soil. As well as Tite has them functioning at the moment, Brazil's stardust, goalscorer and main inspiration remains Neymar. Which is why the PSG man getting back to full fitness and firing on all cylinders as quickly as possible is crucial – he did a glimpse that he could already be back to his best with a nice goal against Austria in a friendly.

The two European nations – Serbia and Switzerland – should pose the biggest threat to Brazil in this Group E. Neither Switzerland nor Serbia have the big stars in their lineup, but they do have a strong and experienced squad, who know how to perform on a big stage.

Group A and B squad lists

Group F:

Germany, Mexico, Sweden, South Korea:

Obvious favourites again in this group, with the defending champions Germany, even if they haven't had the smoothest of preparations coming into this World Cup, expected to ease through to the round of 16. The strength in depth that Germany have was evident when Leroy Sane, who was one of the best players in the Premier League this season, was left out by Joachim Low, with the manager preferring the equally exciting Julian Brandt.

Group C and D squad lists

Mexico are always a dangerous side, with plenty of steel and verve in their squad, and even without Zlatan Ibrahimovic, Sweden have quite a few weapons up their sleeve, chief of them being RB Leipzig's Emil Forsberg.

Group G and H squad lists

South Korea will be the team that many tip to finish bottom of the group, but they do have World Cup pedigree, and in Son Heung-min a forward coming off a brilliant club season with Spurs.
