Wenger admitted after the match that his side now face a major challenge climbing above Chelsea and Tottenham to finish in the final Champions League qualification berth, but ahead of the double-header with Ostersunds in the last 32 of the Europa League, the Frenchman claims that now is not the time to panic.
"Prioritise the Europa? It's too early. Football is not about switching off for three games and switch it on for one," he told reporters at his post-match presser. "Manchester United decided that once they were in the semi-final [last season], we are far from the semi-final. I think we have to fight to have a chance to come back.
"For me it's a very disappointing result. The priority has to be to be in the Champions League through the Premier League. I'm not a great fan of qualifying for the Europa League through the Champions League. If it's an opportunity we have to try and take it as well, but the priority is still the Premier League."
Arsenal, who travel to Sweden next Thursday for the first leg of their European tie, have now gone nine games without a clean sheet in the league - their worst such run since 2002.
