Olympiakos are close to pass in the next round of Uefa champions league (they done it once in the past)they will have great atmoshere in Georgios Karaiskakis stadium . They will do everything to keep at least the draw and then they will look to score , so they will look after their defence . On the other hand the Germans (Werder Bremen) want only to win so they make their plans for the next round of Uefa Champions League . I think Bremen are not going to play to aggresive and they will also look their back and then they search to score at least one Goal . The germans are not in very good shape thats why they are going to be very careful . Olympiakos are playing on sunday a derby against Aek athens and thats a reason also to play careful and not with all their power . So from my analysis its gonna be a very close and careful game and the first think that both teams are going to look up is their defence .
