With the league phase of the Women's Champions League drawing to its dramatic conclusion on Wednesday night, plenty is still to be decided - including whether there could be an all-English play-off double header on the way in February.
All three of England's representatives - Chelsea, Manchester United and Arsenal - are guaranteed of reaching the knock-out play-offs, but under the newly introduced format there's an entirely realistic chance of two facing one other for the chance to reach the quarter-finals.
If the league phase were ended today, it would set up a play-off meeting between Arsenal and Man Utd. Of course, there are plenty of possible permutations to change that across the nine matches kicking off simultaneously on Wednesday evening. But there are eight possible combinations where they - or Chelsea - could end up in the play-off round against another English club.
Only four teams will automatically qualify for the last eight with unbeaten Chelsea currently third in the standings, but sitting just a point clear of the chasing pack.
Victory at Wolfsburg, who have already thrashed Man Utd 5-2 in this season's tournament, will guarantee their progression although a point may well still be sufficient given their vastly superior goal difference to their rivals. Even in a worst-case scenario, the lowest they can finish in the league phase is eighth, the last of the seeded play-off sides.
That position is currently occupied by Arsenal, who face the lowest-ranked side in the competition OH Leuven in their final game. That being said, the European minnows have lost only one of their five games to this point. The Gunners need to make up a point on at least four of the teams above them and so must win to keep their faint automatic hopes alive.
They sit ahead of ninth-placed Man Utd on goal difference. Marc Skinner's team face an almost identical task but also have the Gunners to overtake in order to qualify automatically, and must overturn back-to-back defeats to Wolfsburg and Lyon to do so.
They travel to Italy to face a Juventus side who have impressed in this season's tournament, holding Lyon and narrowly losing to Bayern Munich and currently sitting fourth. Should any of the WSL trio fail to finish in the top four, their priority will be finishing as high in the play-off spots as possible to set up a more favourable run in the knock-outs.
Realistically, anything less than a win may not be enough for either United or Arsenal to finish in the top half of the play-offs as one of the seeded teams.
Teams will be paired as follows for a two-legged play-off, with the higher-rank team playing the second leg at home:
