Brazil vs Belgium
Belgium have revealed a defensive problem in their last game, with Japan scoring two goals in a row. But for they are superior in overall quality, Belgium may find it hard to make a comeback.
On the other hand, Brazil's overall strength is better than that of Belgium. Besides, their attacking quality is great. 
The AH line is -0.50 for Brazil, which is in favor of Tite's team.
Considering both sides' performance in the Last 16 tie, Brazil have a better chance to beat Belgium in normal time.

Uruguay vs France
Uruguay, alongside with Croatia and Belgium, are one of the 3 teams who have won all of their 3 group games, and they have shown their great quality in the Last 16 tie, with a 2-1 win over Portugal thanks to Edinson Cavani's brace. The attacking duo Luis Suarez and Edinson Cavani have mutual understandings and good build-up plays at the front. But whether Cavani can feature in this match is still a doubt.
As for France, they have beaten Argentina in the Last 16 tie, which is reasonable as they have more balanced quality in 3 lines. Kylian Mbappe has exhibited his talents by creating 3 goals. Besides, Olivier Giroud and Antoine Griezmann also have played an important role. This French outfit are of great competitiveness, with a variety of attacking approaches.
In conclusion, France are expected to win this game within 90 minutes.

Brazil vs Mexico
Brazil have got 2 wins and 1 draw in the group stage, with 5 goals scored and 1 conceded, during which Philippe Coutinho has bagged 2 goals and 1 assist. He is the Brazil player with the best performance in group games. Besides, Brazil have already remained unbeaten for 14 successive matches in all competitions.
As for Mexico, they have made into the knock-out stage as the Group F runners-up after beating defending champions Germany in the 1st game.
Both sides have 5 encounters since 2010, and Brazil are superior by getting 3 wins, 1 draw and 1 loss. Besides, Mexico's core defender Hector Moreno will be suspended in this game due to his 2nd yellow card in the last group fixture, which will pile pressure on Mexico's defensive line. So Mexico can hardly halt Brazil's attacks in this match.
In conclusion, I believe Brazil are expected to grab a resounding win in this match.

Belgium vs Japan
Undoubtedly, Belgium are in a golden age of their football history. Their stars are getting team spirit after World Cup 2014 and Euro 2016, which can be seen from their mature performances on the pitch. In terms of strength and experience, they are capable of getting into the semis and even the final.
On the other hand, Japan have shown their improvements so far. As one of the top Asian teams, they establish their status in the world with the past games. Besides, players like Shinji Kagawa and Makoto Hasebe already consolidated their positions in their clubs.
In terms of lineup, Belgium are clearly stronger. Moreover, Japan have been terrible at playing against European teams that have better physical conditions.
The AH line of this game is Belgium (-1.25), which is in favor of them. Therefore I believe the Red Devils are expected to win this game.

Karlsruher SC vs Erzgebirge Aue
This game is crucial for both sides' future, so they are all motivated.
Karlsruher are great in Bundesliga 3 with a solid defense. Although Aue are from a higher level division, their overall performance was poor. Moreover, their recent form has been not so ideal.
Therefore Karlsruher should be supported in this game.
