Barcelona play host to Borussia Dortmund on Wednesday night with both sides looking to cement their place in the round of 16 before matchday six.
Through four games in this year's 'group of death', Barcelona lead the pack with eight points while BVB hold a three-point lead over Inter after their stunning comeback against I Nerazzurri on matchday four.
Wednesday's hosts had a chance to wrap up qualification last time out, but Ernesto Valverde's men failed to break down a resolute Slavia Praha backline and were forced to settle for a 0-0 stalemate.
Despite being top of La Liga, it's fair to say that the upcoming week will go a long way in determining Valverde's future at the club after several sub-par performances this season. A win against the German giants on Wednesday and a good showing on Sunday against Atletico, however, should be enough to secure his job in Catalonia for the time being.
Speaking of under-pressure managers, Lucien Favre has a lot to prove to the Dortmund hierarchy after recent results. A battering in Der Klassiker and a point at home to rock-bottom Paderborn after being 3-0 down has seen the pressure mount rapidly on the Swiss coach.
With everything to play for on Wednesday night, we're in for a cracker. Here's 90min's preview of this Champions League showdown.

The home side will be without both of their starting full-backs with Nelson Semedo (calf) and Jordi Alba (hamstring) ruled out of action for the next couple of weeks. This means we should see former Betis man Junior Firpo start on the left while Moussa Wague and Sergi Roberto will battle it out for the right-back slot.
Valverde will also be forced to delve deep into his centre-back options as Gerard Pique - who picked up his third booking of the group stage against Slavia - is suspended for this one. It also looks unlikely for Clement Lenglet (calf) to start on Wednesday, leaving Samuel Umtiti and the seemingly out of favour Jean-Clair Todibo as their best options. However, 20-year-old Ronald Araujo is also in contention to partner Umtiti.
The away side will likely be without former Barca striker Paco Alcacer (knee), while Jacob Bruun Larsen (knee) and Thomas Delaney (ankle) have already been ruled out.
|Barcelona||Ter Stegen; Roberto, Todibo, Umtiti, Firpo; Busquets, Vidal, De Jong; Messi, Suarez, Griezmann.|
|Dortmund||Burki; Piszczek, Hummels, Akanki, Hakimi; Weigl, Witsel; Sancho, Brandt, Hazard; Reus.|
Head to Head Record
The reverse fixture in Dortmund was dominated by the hosts and if it wasn't for a Marc-Andre ter Stegen masterclass in between the Barca sticks - which included a ridiculously cool penalty save from Reus - BVB would've run out comfortable winners.
Before that 0-0 draw back in September, BVB and La Blaugrana have played each other only twice, in a two-legged UEFA Super Cup meeting in 1998 - after the pair triumphed in the previous season's Champions League and Cup Winners' Cup, respectively.
European champions Dortmund lost the tie 3-1, going down 2-0 at Camp Nou as Rivaldo and Luis Enrique netted for the La Liga giants.
A 2-1 win away at Leganes saw Barcelona maintain their goal difference lead over Real Madrid - who are slowly starting to find their groove - at the top of La Liga. Second-half strikes from Luis Suarez and Arturo Vidal saw the Catalans overturn an early deficit and record just their third win away from home in the league this season.

After a bright start to their Bundesliga
Dortmund fans will hope that Favre can turn it around and help BVB rediscover the form that they displayed in the first half of last season. However, his time is running out and defeat here against a weakened Barca side could prove to be the final straw for the 62-year-old.
|Leganes 1-2 Barcelona (23/11)||Dortmund 3-3 Paderborn (22/11)|
|FC Cartagena 0-2 Barcelona (13/11)||Bayern 4-0 Dortmund (09/11)|
|Barcelona 4-1 Celta Vigo (09/11)||Dortmund 3-2 Inter (05/11)|
|Barcelona 0-0 Slavia Praha (05/11)||Dortmund 3-0 Wolfsburg (02/11)|
|Levante 3-1 Barcelona (02/11)||Dortmund 2-1 Monchengladbach (30/10)|
This has the makings of a cracker with both sides vulnerable at the back for different reasons. Dortmund have structurally been all over the place defensively and their lack of pace - which should be helped with the return of Manuel Akanji - has been exposed by opposing front-lines.
But, with Lionel Messi
Prediction: Barcelona 3-2 Dortmund
