Mexico bagged their second win of the World Cup as goals from Carlos Vela and Javier Hernandez steered them to a 2-1 win over South Korea, with a stunning strike by Heung-Min Son coming too late to save his side. With South Korea's need to earn three points, and with Mexico's ability on the counter-attack, this should be a wide-open, entertaining game.
They took the lead in Rostov-on-Don through Carlos Vela's penalty - the 14th of the tournament already - on 26 minutes after Jang Hyun-soo's handball.
All-time top scorer Javier Hernandez sealed victory in the second half, finishing off an unstoppable move from breakout player Hirving Lozano.
If South Korea go behind, too, they are not as likely to score as Germany were.
Mexico is the betting favorite, and it would be extremely hard to argue for anything else after El Tri's tremendous performance against Germany, but teams with their backs against the wall can be unsafe.
Vela coolly hands Mexico the lead from the spot.
Chicharito also recorded an assist in the first game, setting up Lozano for his goal against Germany. "And we can play entertaining football and hopefully gain a lot of fans around the world".
So, two teams with two very different mindsets heading into this one.
South Korea threatened again nine minutes later, Son breaking clear of Mexico's line before letting rip with a low drive that Hector Moreno did well to keep out. Joshua Kimmich and Marvin Plattenhardt were both used as attacking outlets by the world champions, but this left Die Mannschaft exposed.
The hapless Koreans, who have no points after two games and have only won one of their last 11 World Cup fixtures, will be eliminated if Sweden draw or win against Germany. Only Russia's Roman Zobnin (eight) has more.
Not to be outdone, Cho was at his best soon after, South Korea's goalkeeper lunging to his right to tip Hernandez's goal-bound shot wide.
Löw had rung the changes before the game, bringing Reus and Sebastian Rudy into the starting line-up at the expense of Mesut Ozil and Sami Khedira - the first time the Germany coach has left the Arsenal midfielder out of the starting XI at a major tournament since 2008.
