Celtic will be without Georgios Samaras, Kris Commons and Gary Hooper for their trip to face Rennes in the Europa League.
The trio did not travel with the Celtic party due to injury, leaving manager Neil Lennon with limited options.
But assistant Johan Mjallby insists his side still have enough attacking options to get a result in France.
"We still think we have a good number of players whose strength is in attack," he said.
"Usually we are an attack-minded team so I'm not sure that we can sit back and defend, it is not in our nature, especially when we have been quite poor defensive-wise in recent weeks."
Hooper picked up an ankle knock in Celtic's 3-3 draw at Kilmarnock at the weekend, Samaras has failed to recover from a bruised bone, while attacking midfielder Commons picked up a calf injury in training. Defender Badr El-Kaddouri is cup-tied for the competition.
Celtic face Rennes in Group I on Thursday looking for a much-needed victory, having won just four of their last 12 games.
In contrast, the Breton side have been beaten just once in their last seven domestic matches.
Their manager Frederick Antonetti has chosen to rest star player Yan M'Vila for the tie, despite the midfielder approaching a century of appearances for the club at the age of just 21.
