Bremen - FC Bayern München could open up a 14-point lead at the Bundesliga summit with victory away to in-form SV Werder Bremen on Saturday (kick-off 15:30 CET/14:30 GMT).

The defending champions are unbeaten since losing to second-placed VfL Wolfsburg on Matchday 18, but are unlikely to have things entirely their own way at the home of their old rivals from the banks of the Weser. previews the north-south action...

The visit of runaway league leaders Bayern will provide Bremen fans with a useful indication of just how far their side have progressed since Viktor Skripnik took charge last autumn. The Green-Whites have been one of the Bundesliga's form sides in 2015 and go into the game just five points outside the European places.

12-goal leading scorer Franco Di Santo misses out after collecting his fifth yellow card of the campaign in last weekend's 1-0 win at SC Freiburg. Davie Selke (r.) is the most likely replacement for the in-form Argentine, unless Viktor Skripnik chooses to stick an extra man in midfield such as Felix Kroos or Cedrick Makiadi instead.

Arjen Robben (l.) and Franck Ribery have been ruled out with thigh and ankle problems respectively. Medhi Benatia could return to the heart of the back four, while captain Philipp Lahm could feature for the first time since fracturing an ankle in training last November. Xavi Alonso, however, is suspended.

Zlatko Junuzovic has been in impeccable form this term, striking up a fantastic understanding with the Bremen forwards. The Austrian midfielder is also a dab hand at set pieces, with all five of his goals in 2014/15 coming from direct free kicks. Bayern certainly won't want to concede many fouls in their own half with him around.

Thomas Müller took his league tally for the season to 11 with a cool brace against Hannover on Matchday 24 and he was at it again in midweek, netting twice against FC Shakhtar Donetsk in the UEFA Champions League. The 25-year-old has a habit of popping up in all areas of the pitch and won't rest until Bayern are home and hosed.

Skripnik (head coach): "Those who are scared should stay in the changing room. The Wolfsburg game was a great example of this. You don't get anywhere without being brave. No motivation is needed. Everyone is looking forward to the game."

Pep Guardiola (head coach): "It's a challenge, I'm looking forward to it. [Bremen's] results speak for themselves [..] Lahm could play a few minutes in Bremen, but he should be back to his best after the international break when Thiago [Alcantara] should return to team training again."

Bremen returned to winning ways following their 1-1 draw at FC Schalke 04 and 5-3 home defeat to VfL Wolfsburg with a 1-0 win over Freiburg. Bayern, meanwhile, followed up their fifth successive Bundesliga win of the year at Hannover by booking their place in the quarter-finals of the Champions League thanks to a 7-0 drubbing of Shakhtar.

Bayern have won their last ten on the spin against Bremen, thrashing the Green-Whites 6-0 at the Allianz Arena earlier in the campaign. They ran out 7-0 victors at the Weserstadion last term, with Werder's last home win over the men from Munich coming in October 2006.

Possible line-ups:

Bremen: Wolf - Gebre Selassie, Prödl, Vestergaard, Garcia - Bargfrede - Fritz, Junuzovic - Öztunali - Bartels, Selke

Bayern: Neuer - Rafinha, Benatia, J. Boateng, Alaba - Lahm, Schweinsteiger - Müller, Götze, Bernat - Lewandowski
