LONDON (Reuters) - Arsenal must guard against complacency against dark horses FC Basel in their Champions League clash, manager Arsene Wenger said, as the Premier League side look to secure their first victory in the competition this season.
The Swiss champions, who drew 1-1 against Ludogorets in their opening group fixture, have tasted defeat just once in 10 Champions League matches against English teams, and are unbeaten in 12 games this season.
