Johan Djourou insists it would be 'unthinkable' for Arsenal not to make the UEFA Champions League group stage.
The Gunners face a two-legged play-off to make the group stages after they finished fourth in the Premier League.
Arsenal came through this stage in 2009, when they beat Celtic, and Djourou insists that they are focussed on making it through and they are not even thinking about failure.
"We have to be in the Champions League. It would be unthinkable not to be," said the Swiss stopper.
"We've been in this situation before against Celtic and it wasn't ideal, but we got the job done.
"We have to make sure we get through the play-off. We are quite capable of doing it - we have nothing to fear.
"We know last season was not the best but we have a chance to put that behind us now and have some success."
Arsenal have been seeded in the draw which is due to be made at the start of August, but they could still face some tough opposition including the likes of Udinese, Dynamo Kiev or Rubin Kazan.
