Arsene Wenger: We want to 'put things right' after loss to Chelsea

Arsenal manager Arsene Wenger says his side "want to put things right" as they face Olympiakos in the Champions League on Wednesday after their defeat by Chelsea at the weekend.

The Gunners suffered their first loss of the season when they were beaten 2-1 by their city rivals on Saturday.

Despite admitting his players are "still down", Wenger insists Arsenal will improve in time for their home match against the Greek champions.
