Pressure on Germany after draw in first game, while Korea can seal qualification.
Group Group C Fonte Nova Arena, Salvador, Brazil
Key Stat: Three of Korea's eight goals against Fiji were scored by substitute strikers.
Expert Verdict: On paper this should be a relatively comfortable win for Germany, but they will need to increase their performance levels after looking below-par against Mexico. The game will also be a change of pace for Korea, who brushed Fiji aside very easily in their first game. There are likely to be plenty of goals here, but Germany should win.
Germany could make changes to their team after drawing their first game of the tournament 2-2 against the defending champions Mexico, leaving them with a lot of work to do to qualify.
Gnabry and Ginter scored the equalisers for the Germans, who lined up in a 4-2-3-1 formation in their Group C opener. Gnabry is likely to come into the team after making a positive impact against Mexico, with Goretzka expected to drop out of the XI. Petersen could also replace Selke.
Horn, Toljan, Sule, Ginter, Klostermann, Bender, Bender, Gnabry, Meyer, Brandt, Petersen.
An 8-0 thrashing of Fiji has put Korea in a fine position in Group C, although Germany will provide a much sterner test of their abilities. There is little need to change the winning team, with , Kwon and Suk hitting doubles, while Ryu completed his hat-trick with an injury-time goal.
Suk started that match on the bench and his goalscoring exploits as a substitute could mean he comes into the Korean team, potentially at the expense of Hwang, who he replaced last time out, with Son also in contention to earn a start after converting a penalty against the luckless Fijians.

There is not a lot of history between these two nations, with just three matches on record as having been played by Korea and Germany over the years.
The most recent of those games was a friendly in 2004, Korea coming out on top with a 3-1 win.
However, in both times there has been a competitive match between these two Group C sides, Germany have won, with victories at both the 2002 and 1994 World Cups, both of which were recorded by a single goal.
Germany have been made strong favourites by the bookmakers, but Korea's confidence levels will be through the roof after their destruction of Fiji in their first match at the Olympics. The quality in the Germany squad should see them through, but there were a few worrying signs in their draw against Mexico, which might just open the door for a shock result.
A price of 4/9 means there is little value to be found in backing Germany to get their first win of the Olympics, while Korea can be backed at 7/1 to make it two victories out of two in Brazil. The draw is also at a big price - offered at 3/1 - which may tempt those who are expecting a surprise here. Goals seem inevitable - there were 12 goals in the two games involving these sides on Thursday - so over 2.5 goals stands out at 4/7, while over 3.5 goals may be tempting at a price of 6/4.
