I honestly doubt it... From those three, I think only Bittencourt is set to stay, and that's just because his knee injury. Toprak might stay or go to Turkey, I think. I can't really see Maxi Eggestein staying, considering he just recently changed his agent in order to attract more attention from foreign clubs. After all, we also sold our captain in the middle of the season last time...
Also, the captain and vice captains were not chosen by the manager this time, but by the team instead; it's the first time it happened in Bremen! So I think it was just the case of the team voting for those with most experience, leadership skills and highest respect levels within the squad.
