Joel Campbell is confident Arsenal can overcome a long injury list and achieve the required result against Olympiakos on Wednesday night.

The Gunners head to Athens without the likes of Alexis Sanchez, Santi Cazorla, Francis Coquelin, Mikel Arteta, Jack Wilshere, Danny Welbeck and Tomas Rosicky but Costa Rican attacker Campbell suggests it is the fringe players who can do the job for the North Londoners as they go after a two-goal win to ensure their place in the Round of 16 of the Champions League.

"We have had bad luck with injuries," Campbell told the IBTimes UK.

"There have been injuries for players who are very important to us, but we are a big club and we have great players (to cope with the situation). We have to step up and move forward.

"It's not just me, the whole team are leading the way, it's the only way to go. All of the players are giving their best and it's paying off on the field."

Regarding his own role, Campbell insists he is happy to be deployed anywhere upfront by Arsene Wenger.

"I can play in three positions: left, right and in the middle of the attack," he added.

"Wherever the boss plays me I try to do my best."
