Cape Town - Arsenal manager Arsene Wenger admits that his team are low on confidence following their 2-1 defeat to Swansea City at the Emirates Stadium on Wednesday.
Joel Campbell put the Gunners ahead after 15 minutes, but Wayne Routledge had the Swans level just past the half-hour mark before Ashley Williams tucked home Gylfi Sigurdsson's free kick in the 74th minute.
"It's a very disappointing result," Wenger said.
"The players are very down but we have to respond to that. It was a very unlucky defeat because we created many chances, we were unlucky in our finishing and they only had two shots on target which were both goals.
"We focus on our job and come back reminding ourselves that we have some quality as well. Of course we have to analyse it as well and bounce back. We have a big game in three days."
Back-to-back league defeats to the Swans and Manchester United have left the Gunners six points adrift of league leaders Leicester City and three behind Tottenham, who they face in the north London derby at White Hart Lane on Saturday.
"At the moment I am worrying about our results. We just lost three games and that is always a very disappointing moment for the team," Wenger added, referring also to their 2-0 loss to Barcelona in the Champions League.
"At the moment, I believe that we need to get back to positive results before we speak about the Championship, which is at stake at the moment. It is very difficult as it is unpredictable. Manchester City lost, Tottenham lost. It is very difficult to predict what will happen in this league."
