What's fun about all this is that if Sweden and Germany win next game, we have a three way tie for 1st place in Group F. Mexico doesn't have an insurmountable goal differential, either.
Germany pressed hard for the victor but it looked like Sweden had held out until Kroos curled in a free kick from a right angle to spark scenes of huge relief among the Germans.
Germany, who had influential defender Jerome Boateng sent off for a second yellow card, were far from convincing and put in a nervous display after a barrage of criticism following defeat to Mexico.
He kept Germany alive in the World Cup and established himself as the undisputed leader of the team at a time when others of his generation had failed to do so.
With Germany getting in behind Sweden's full backs at will and fizzing passes across the box, it looked like a matter of time before they scored, but Toivonen's goal gave Sweden breathing space. It was a thing of beauty.
South Korea's World Cup hopes may just have been dealt another blow after a 2-1 loss to Mexico on Saturday, with their captain Ki Sung-yueng leaving the match on crutches with a leg injury. Germany will take on Korea, while Sweden battles group-leader Mexico.

Kroos passed the ball short to Reus, who stopped it for his team mate to curl it into the top far corner of the goal for a sensational victor deep into stoppage time.More news: Brazil, Costa Rica raise eyebrows by playing in away kits

Tottenham Hotspur forward Son Heung Min curled in for South Korea three minutes into stoppage time but it was too late to mount a fightback.
The holders are left needing to better Sweden's result in the final round of games - against South Korea and Mexico respectively - if they are to go through, while the chances of Germany meeting Brazil in the round of 16 boosted by Mexico's earlier win over South Korea.
"We missed a couple of good chances but I appreciated the spirit of the team, we never lost hope of winning the match".
