Manager Arsene Wenger maintains his bruised Arsenal squad cannot afford to feel sorry for themselves if they are to bounce back from a nightmare opening day defeat by Aston Villa and keep alive their Champions League dream in Turkey next week.
The Gunners were booed off after they lost 3-1 at home to an industrious Villa side, who were helped somewhat by a controversial second-half penalty and the dismissal of Laurent Koscielny for a second yellow card.
Given the criticism for failing to land any major summer transfer targets despite having millions in the bank, it was hardly the ideal warm-up ahead of Tuesday night's first leg of a crucial Champions League play-off against Fenerbahce at the intimidating Sukru Saracoglu stadium.
