Arsène Wenger believes Arsenal must maintain their focus following their recent \"blip\" against Wigan to ensure they finish in third place. Wenger’s side hold a five-point advantage over Tottenham and Newcastle but have played a game more after Monday’s disappointing defeat at Emirates Stadium. But, with only third place guaranteeing a place in next season’s Champions League group stages, Wenger has called for focus ahead of Arsenal’s final four matches of the campaign. “We had a little blip twice I believe for mental reasons,” he told Arsenal Player. “Maybe subconsciously we thought, \'Ok, maybe that would be a little bit easier\' and if you do not keep a clean sheet against these teams then you put yourself in trouble. “You give any team in the world a two-goal advantage and it is difficult. Many times we have come back but not always. “I don\'t know [how many more wins we need], we just want to win the next one. I believe our target is just that. We have to think that we have been on a great run, we have a fantastic opportunity but we also just need to focus on the next game and win it. “Only the third place guarantees you to be in the Champions League anyway.”
