The Allianz Arena hopes for a spectacular comeback from the Bavarians, whilst the Catalan giants are keen to secure their place in the final.
Last week at the Camp Nou, an impressive late flourish led by Argentine star Lionel Messi, saw Barcelona secure an excellent 3-0 advantage against Bayern Munich.
Although it's true that Barcelona are now seen as clear favourites to progress, Bayern Munich will undoubtedly be expected to throw everything at their rivals tonight, aiming for the kind of spectacular comeback they achieved in the quarter-finals, against FC Porto.
Barcelona will certainly be wary of that potential threat, but insist that they aren't going to defend at the Allianz Arena, and will be looking for goals themselves, in order to finish the job.
As such, Barça boss Luis Enrique has named the same starting eleven as the first-leg of the semi-final, believing they're best suited to deal with the best their German opponents can offer.
The only change for the Catalans comes on the substitutes bench, with Mathieu replacing Vermaelen.
Bayern Munich manager Pep Guardiola must be concerned, with his side in the midst of a five-match run of defeats, in all competitions. The Bavarians will surely need to be at their very best, if they're to stand even the remotest of chances, of keeping their Champions League dream alive.
Expected to ring in the changes ahead of the game, Guardiola has instead opted for the same starting eleven, which suffered defeat at the Camp Nou. Whether there are any tactical surprises, remains to be seen.
