Per Mertesacker believes Arsenal have the perfect chance to demonstrate their inner strength against QPR on Saturday.
The Gunners slipped to their second defeat in five days when they were beaten 2-0 by in-form Schalke in the Champions League on Wednesday night.
Mertesacker says the team were disappointed with their display at Emirates Stadium, but must now turn their attention to the coming London derby.
“We have had a difficult week, our results were kind of an accident, now we have to find our game again,” the defender said. "The international break was kind of a killer for us. We have to find our strength again quickly.
"We have the potential in us, but first we have to fight. We have to learn quickly from what happened [at Norwich last weekend] and against Schalke. If we do not find these solutions, it is going to be difficult in the Premier League and the Champions League.
"It is our task now to find our self-confidence, we have great players with great potential. So it will be good to have a game in three days so we can show our potential again.
"We will try to be positive before the next game. In our training sessions we will look to get our confidence back. Sometimes you need one game to find your strength and quality, so let's do it on Saturday."Copyright 2015 The Arsenal Football Club plc.
