Sweden, who beat South Korea 1-0 in their first match, have three points and were unlucky not to collect another from their game with Germany, who they had been holding to a draw until Toni Kroos' last-minute victor.
South Korea originally planned to have outdoor training with all players, expect for the injured Park Joo-ho, in St. Petersburg, but because of cold weather and rain, the coaching staff chose to protect their best 11.
Germany coach Joachim Loew described his defending champions as "lucky" after Kroos's free-kick revived their Cup hopes.
"We can not afford to get caught up in all this, we have to continue our job and stay humble, of course we should enjoy this but tomorrow we start working again".
Manuel Neuer saved the Germans from being 2-0 down at halftime, diving acrobatically to deflect Berg's header from Sebastian Larsson's stoppage-time free kick.
Then, in the final part of the game, Germany had to play a man down after Jerome Boateng was sent off with a red card.
Rose Leslie Wears Lace Dress to Her and Kit Harington's Wedding
The duo, who began dating back in 2012, broke the news of their engagement by placing an announcement in The Times newspaper. Thankfully that wasn't the case at the wedding of Kit Harington and Rose Leslie in Aberdeenshire, Scotland this morning.
"It will be a very hard game and there will be a lot of counter-attacks from South Korea". Germany's lackluster opening performance and loss against Mexico was unexpected.
By his own admission, Kroos was at fault when he gave the ball away, which led to Ola Toivonen's first-half goal for Sweden, putting Germany on the brink of a World Cup exit. He has been living up to expectations in Russian Federation with two solid appearances as a substitute.
Mexico's strong World Cup has forced the Mexican press to change their tune, and even Sanchez had to praise Osorio's tactics against Mexico.
With its chances of qualification already slim, South Korea took a blow when captain Ki Sung-yueng was ruled out with a left calf injury.
- Mexico has never won three consecutive matches at the World Cup and could become the first CONCACAF team to achieve this feat in World Cup history.
So it was up to Kroos to carry the hopes of Germany on his shoulders and revive their hopes of reaching the knockout stage ahead of their last group match against South Korea.
