Former Arsenal striker John Hartson says 鈥渃omplacency鈥� is to blame for the Gunners as they battle to keep their Champions League hopes alive.

In September they were beaten 2-1 by Dinamo Zagreb and 3-2 by Olympiakos when they rested several key players.

Arsene Wenger鈥檚 side need to win their two remaining group games and hope other results go their way to make it to the knockout stages.
