World Cup 2018: Sunday's Match Odds and Updated Group Predictions

The oddsmakers are firmly in the camps of Brazil, Germany and Serbia on Sunday, predicting three one-sided 2018 FIFA World Cup matches in Groups E and F.

Brazil and Germany are arguably the favourites for the trophy, and Costa Rica have been thoroughly outplayed in their last few friendlies, explaining why the Serbs are such heavy favourites.

Odds

Costa Rica (43-10) vs. Serbia (7-10), draw (13-5)

Germany (11-20) vs. Mexico (11-2), draw (29-10)

Brazil (8-25) vs. Switzerland (21-2), draw (39-10)

Group E

Switzerland's high odds against Brazil are perhaps a little surprising considering the Europeans enter the tournament ranked as the sixth-best team in the world, according to FIFA.

The team impressed in their final friendlies ahead of the World Cup, holding Spain to a draw and smashing Panama 6-0 in March.

Brazil's fans are not expecting an easy outing:

The Selecao have also impressed of late, and Neymar appears to be in fine form, only recently returning from injury. This match has the potential to be one of the group stage's best, but with Switzerland's solid defensive reputation, goals may be hard to come by.

Costa Rica were not afraid to attack Belgium in their final friendly, but they paid dearly for it, losing 4-1. The CONCACAF side also struggled against England but appear set to stick to their ways rather than adopt a defensive mindset.

That's good news for neutral fans and Serbia, who have plenty of scoring potential in their side, with Sergej Milinkovic-Savic, Aleksandar Mitrovic and Dusan Tadic all expected to play starring roles.

Prediction: Brazil and Switzerland share the spoils on the opening matchday and qualify from Group E, with the Selecao taking the top spot on goal difference.

Group F 

Germany and Mexico will contest the only Group F match of the day, with Sweden and South Korea going head-to-head on Monday.

Die Mannschaft are the champions, and while they showed some signs of weakness in their final friendlies before the tournament, the Germans are expected to turn things up a notch on the big stage and easily win Group F.

Mexico have bags of talent, but their forwards have struggled tremendously of late, picking an awful time to go into a slump.

El Tri are not planning on changing their tactical setup, however:

These teams should like their chances of advancing to the next round, although Mexico likely wish they could have started their campaign against Sweden or South Korea―instead, they will have to chase at least one of those two if they lose to Germany.

Prediction: Germany beat Mexico and cruise to the next round, while Mexico narrowly hold off Sweden for second place.
