Chilean tempers started to fray, and approaching the hour mark Joshua Kimmich squared up to Vidal, who pushed the German away. The Bayern Munich team-mates were both booked.
Then Werner was left clutching his jaw after an elbow in the face from Jara near the touchline, the Serbian referee deciding to award a yellow card to the defender after reviewing the incident.
The South Americans battered the German goal in the final 20 minutes but Sanchez’s shot was blocked and Ter Stegen then saved from Eduardo Vargas.
With time running out, both Vidal and substitute Angelo Sagal fired over the bar, but the German defence held firm.
