Germany goalkeeper Manuel Neuer has claimed that his team do not need to change players .
The world champions were beaten 1-0 by Mexico in their opening Group F match.
"Every match is like a final. We are convinced we can do it," said Neuer.
"We are frustrated and disappointed. Now it is up to us to react.
"We know the players on the pitch can deliver and take responsibility so, for me, it is more about readiness to play this tournament at 100% and not about personnel and changing players."
If Germany lost to Sweden, it could mean the earliest exit for the four-time champions since the 1938 World Cup.
Despite the pressure and ongoing discussions, Manuel Neuer said none of the players are “shiny away from responsibilities.”
"We talked about what we must improve," he said. "We cannot change the result of the game against Mexico or of the warm-up games. Now we have to show what made us strong in the past.
"We have tried to find points that we can improve and say our opinions honestly. The courage and the self-belief was missing.
"I am convinced we can show and will show a different face against Sweden. It is not very easy to just turn the switch. We have to work on it on and off the pitch."
