Arsenal have a mountainous task to climb in surmounting the 2-0 deficit built up by Bayern Munich in the first leg of their round of 16 encounter, but it's not a challenge outside their grasp just yet.
The North Londoners travel to Germany this week in the knowledge that their last trip to the Allianz Arena resulted in a 2-0 triumph just last year.
As English and German top-flight contenders prepare to collide, we've broken down some of those players who will be especially important in ensuring Arsenal come away from Bavaria with their European hopes still intact.
BBC Sport have confirmed that Laurent Koscielny will be in contention to make his return from fitness in Munich, having picked up a hamstring injury of late.
Granted, a centre-back partnership of the Frenchman and Per Mertesacker proved insufficient in restraining Der FCB's attack last time out, but any hopes of revival rest on that first-choice defence being allowed to redeem itself.
Without Koscielny, Wenger would be forced to utilise an inferior replacement such as Thomas Vermaelen, lacking in match fitness and having sat on the bench for the majority of the campaign thus far.
Koscielny's ball-playing abilities protruding forth from Wenger's back line will be a much-needed commodity if Arsenal are to be able to stage an assault on the ball possession in Germany.
Mesut Ozil's summer arrival seemed to have an impact on the consistency of Santi Cazorla's form at the Emirates Stadium, but the Spaniard has moved from strength to strength of late.
Cazorla was taken off in the first half of the leg but can look forward to having a more prominent impact this time around.
The Telegraph's Henry Winter praised the playmaker for his display against Everton over the weekend:
In the last two months, Wenger's midfield puppeteer has managed to quadruple his Premier League scoring total this season, and if Olivier Giroud is to leave a mark on Tuesday, Cazorla will be key to serving up scoring chances.
Having returned to scoring form during The FA Cup win over Everton on the weekend, Ozil has picked the right time to pick up morale.
The German international received criticism for his innocuous performance in the first-leg encounter with Bayern, failing to penetrate the Bavarians' defence or cause much disruption with his playmaking.
Agence France-Presse's Ryland James quotes Wenger as backing his asset to bounce back, though:
The Gunners will be hoping that Ozil is capable of returning to his creative best at the Allianz Arena on Tuesday, a ground in which the attacking midfielder has scored twice during his career already.
