Munich - Top hosts bottom on Saturday as league leaders FC Bayern München welcome struggling SV Werder Bremen to the Allianz Arena (kick-off 13:30 GMT/15:30 CET). looks ahead to Werder's seemingly impossible Matchday 8 challenge...

With Bayern already enjoying a four point lead at the top of the Bundesliga, they will be looking to consolidate that comfortable position by avoiding any upsets on Saturday. Bremen, conversely, are desperate to pick up an unlikely three points that could move them off the bottom of the table and towards safety.

Pep Guardiola was boosted by Franck Ribery's return to full training this week - although the French wide-man will probably start on the bench here. Thiago, however, suffered a fresh tear to his knee ligaments on Wednesday, meaning his comeback from injury is back to being months, rather than weeks away.

Bremen have no new injury news to report following the international break and are boosted by Theodor Gebre Selassie's return to training, although this game probably comes too soon for him. After experimenting with Eljero Elia as a second striker, coach Robin Dutt is likely to move him back to his favoured left-wing slot.

Arjen Robben looks to be back to full fitness and seems to be returning to form, too, having found the net twice last time out against Hannover 96. Always a major threat, the Dutch winger is particular dangerous against Bremen - he has won all 6 games against them in all competitions, scoring in every single one (seven goals in total).

Keeper Raphael Wolf will be anticipating a busy day repelling swarms of Bayern attackers; he will have to be at his best if Bremen are to get anything from the game. The custodian is yet to keep a clean sheet this season, conceding at least twice in five of his seven Bundesliga outings, but what better time to change that stat?

Zlatko Junuzovic, Bremen midfielder: "Nobody is betting a cent on us. We have nothing to lose and can play freely."

Philipp Lahm, Bayern captain: "If you've just come back from injury, then suffer another setback, it's very frustrating. I'm incredibly sorry [for Thiago]."

Bayern have won their last four games in all competitions, including a 4-0 victory at home to Hannover last time out, and they've also gone nine competitive games without conceding a goal. Bremen, meanwhile, are without a league win this term, though they did pick up a point in their last match against SC Freiburg.

Bayern are unbeaten in the last eleven encounters between these clubs, scoring a whopping 18 goals in the last three match-ups alone. Bremen have to look back to 2008 for their last triumph at the Allianz Arena, although that shock 5-2 win may offer them some hope of pulling off another surprise.

Possible line-ups:

Neuer - J. Boateng, Dante, Alaba - Rafinha, Lahm, Xabi Alonso, Juan Bernat - Robben, M. Götze - Lewandowski

Bremen: Wolf - Busch, Prödl, Lukimya, Garcia - Junuzovic, Makiadi - Bartels, Elia - di Santo, Selke
