The four-time world champions have their backs to the wall and need a result against Costa Rica to move on to the round of 16.
Germany have a calculator in hand as they enter their final World Cup group stage game. The Germans were shocked by Japan 2-1 and then played the game of the tournament against Spain with a 1-1 draw.
On the other hand, Costa Rica bounced back from a brutal 7-0 defeat to Spain with a 1-0 win over Japan. Los Ticos are by no means out of the tournament and if they can pull off a shock win over Germany, it would be a historic knockout round.
Scenarios if Germany and Costa Rica ends in a tie
A draw between the two sides would mean that Germany is knocked out of the competition. Germany can only advance with a win over Costa Rica and a Spanish victory over Japan.
Costa Rica will go through with a win over Germany and could even earn top spot in the group if Japan and Spain draw. A draw will see Costa Rica go through only if Spain defeats Japan. A draw against Germany and a Japan win would almost certainly be the end of Costa Rica in the tournament as they would need to make up a 13-goal difference.
