Bayern Munich can wrap up their second successive title, and it's last-chance saloon for Werder Bremen; if the Northerns fail to beat Bayern, they are down.
While those teams are involved in matters that massively affect their season, the race for fourth is also hotting up and it's anyone's guess to who finishes behind the top three.
1. FC Köln - Turbine Potsdam
It has been a season of woe for the Billy Goats, and their relegation back to the 2. Bundesliga was confirmed last weekend. To compound matters Lena Schurm, Nina Ehegötz and Rachel Rinast have all been confirmed as summer signings for bitter rivals, Bayer Leverkusen. They haven't won since early December and seven consecutive loses since the turn of the year sees them sit on six points - well away from Leverkusen and safety. The question now is, where will top talent Anna Gerhardt end up?
Turbine have had a terrible season by their standards, and are a long way off from finishing within striking range of last year's top three. Goals have been the problem in Potsdam, even with Svenja Huth; with three games to go they have conceded the same amount as last season but the losses of Lisa Evans, Genoveva Añonma and Pauline Bremer have been hard to cope with. Defeat to Jena has hampered their chances of claiming fourth but they are just four points behind a stuttering Sand; it could happen.
Bayern Munich - Bayer Leverkusen
After losing their unbeaten record recently, there is only one thing left on Bayern's mind; finishing off their run to the title this weekend. A shock exit to FC Twente and an even bigger surprise was their Pokal defeat against Sand, the Bavarians will be made to settle for just the league again. There is little doubt Thomas Wörle will already be looking towards next year and planning his summer dealings to bring them up to speed on the European front. However, a point this weekend and a superb title defence will be sealed.
While their hosts can ensure their reign as champions will continue, Bayer Leverkusen are looking to extend their time in the top tier this Sunday. A win over Bayern will make it mathematically impossible for Bremen to catch them, although Die Werkself could lose all of their remaining games and still stay up if Werder don't win all three of their final fixtures. The arrival of the aforementioned Köln trio will bolster them going forward into next season, as they hope to kick on out of the bottom half.
Werder Bremen - SGS Essen
It's now win or bust for Werder Bremen, who simply can't afford anything less than maximum points and a favourable set of results. As unlikely as it is, rest assured the girls in green and white will battle to the very end. Despite an unlikely win against Sand reducing the gap between themselves Leverkusen to just five points, a 4-1 defeat at the hands of Bayer now sees the jump a huge eight with just nine points left to play for. Should they go down, Bremen will fancy their chances of an immediate return.
SGS Essen will be shaking off the cobwebs on Sunday morning, having not played for 11 days when this fixture comes round. They are another one of the clubs that are in the running for fourth and will be desperate to try and claim the 'best of the rest' spot. Lea Schüller will be hoping to continue her impressive form since the turn of the year, and Christine Hartmann is equally keen to curtail her drought in front of goal. This is a game Essen need to win if they are to claim fourth.
SC Freiburg - SC Sand
The battle of the two teams who had broken away from the rest sees Freiburg play host to Sand on Sunday. Both have just one win in their last five games, the hosts' triumph came against 1. FFC Frankfurt before they were beaten by USV Jena last time out; a sign of how inconsistent they have been. A victory here would take them back above Sand, and they'll want to see Lina Magull end her time with the Schwarzwald side on a high.
Sand's fairytale run came to an end against VfL Wolfsburg and although they shocked Bayern in the cup, their league form hasn't been the same since. Given that their aim would have been survival, their current position and a DFB Pokal der Frauen final is a superb effort. Their last few league games will be used to try and find a return to form, as well as capping off a magnificent campaign on a high.
