Arsene Wenger admits vulnerable Arsenal must show some fight to avoid more misery in Wednesday's crucial Champions League playoff first leg against Fenerbahce in Istanbul.

Wenger's team suffered a dismal start to the Premier League campaign as Aston Villa romped to a surprise 3-1 win at Emirates Stadium on Saturday.

Arsenal's lackluster display sparked a furious response from Gunners fans, who left Wenger in no doubt they blame him for failing to fulfil the club's preseason promise to spend big on new signings.
