In recent years Arsenal and Bayern have been virtually inseparable in Europe, having played each other four times in the last five campaigns.
The German giants knocked Arsenal out in the round of 16 in 2005, 2013 and 2014.
Last season the teams met in the group stage, with the Gunners finishing behind the Bavarians after exchanging home victories - Arsenal winning 2-0 in London, before Bayern replied with a 5-1 thumping in Munich.
A narrow loss against Atletico Madrid and a shock defeat to FC Rostov meant Munich finished second in Group D and will play host in the first leg after Arsenal overcame Paris Saint-Germain to win Group A.
The return from injury of forward Danny Welbeck, coupled with the fact that only Borussia Dortmund and Barcelona scored more goals in the Champions League group stages, bodes well for the Gunners' attacking threat.
However, the Germans have some added motivation after Philipp Lahm announced last week that he would retire at the end of the season and the talismanic captain would love to bow out as a European champion again.
The Bundesliga leaders have won 10 of their last 11 matches in all competitions and will come into the game full of confidence, but striker Robert Lewandowski insists they are expecting a tough match.
Franck Ribery is back in training after two weeks out with a thigh injury and could be on the bench for Wednesday's clash, but centre-back Jerome Boateng is still in recuperation from an operation on a chest muscle injury.
From an Arsenal perspective, Mesut Ozil's recent struggles are taking much of the focus as the continued debate about his impact in key games was sparked again following the recent 3-1 defeat to Chelsea.
Bayern defender Mats Hummels launched a strong defence of his Germany team-mate - as well as Gunners boss Arsene Wenger - ahead of the encounter.
However, the playmaker, who has been linked with a switch to Bayern, has not scored since 10 December and Wenger must decide whether to drop him for a more robust midfielder as the North Londoners look to stay in the tie.
Elsewhere, Granit Xhaka is available for selection and Mohamed Elneny is back from the Africa Cup of Nations, and the pair could be preferred to Francis Coquelin for the two spots in Arsenal's double-pivot.
Alex Oxlade-Chamberlain may be fielded alongside them after some encouraging displays centrally in recent weeks in a move that could prompt Ozil to be shifted wide in a remodelled 4-3-3.
Welbeck's pace on the counter and diligent defensive work may see him preferred to Theo Walcott in the other wide berth, with Alexis Sanchez expected to keep Olivier Giroud out once more.
The Gunners will be without Lucas Perez, who is struggling with a hamstring problem, while Santi Cazorla remains sidelined with a long-term Achilles complaint.
David Ospina is set to start in goal ahead of Petr Cech as Wenger sticks to his plan of fielding the Colombian in the cup competitions - much to the bemusement of some critics, such as BT Sport pundit Rio Ferdinand.
Wenger has been at pains to point out the importance of an efficient defensive display in Munich but insisted the change between the sticks will not disrupt his back four.
Skipper Laurent Koscielny took up the theme in a pre-match interview with BT Sport, suggesting that his side would be happy with a goalless draw at the Allianz.
Bayern, of course, will have other ideas.
Who will take an advantage into the second leg?
- This is the first time Bayern Munich haven’t topped their Champions League group since 2009/10. They nevertheless reached the final later that season (0-2 v Inter Milan).
- Meanwhile, Arsenal have won their Champions League group for the first time since 2011/12. It’s also the first time since 2005/06 (when they reached the final) that they remained unbeaten in a group campaign.
- Arsenal have been knocked out in the round of 16 in each of the last six seasons (twice v Bayern Munich) whilst the Bavarians have reached the semis in the last 5 campaigns.
- Bayern Munich have won their last 15 home Champions League games (53 goals scored, 8 conceded), the longest winning run in the history of the competition. Real Madrid are the last team to beat them at the Allianz Arena, in April 2014 (0-4).
- Arsenal have been defeated in the first leg of their Champions League round of 16 tie in each of the last five seasons.
- Robert Lewandowski has scored 14 goals in his last 12 Champions League games at the Allianz Arena. The only time he failed to find the net in those 12 games was against Benfica last April.
- Olivier Giroud has scored in three of his last four Champions League games against Bayern Munich, including in two of his last three away against them.
- Arsène Wenger and Carlo Ancelotti have managed 329 games between them in the Champions League (182 & 147 games respectively), putting them second and third behind Alex Ferguson (190 games).
- The only previous Champions League encounter between Ancelotti and Wenger was in the 2007/08 Champions League round of 16. Wenger’s Arsenal saw off Ancelotti’s AC Milan 2-0 on aggregate.
