Bremen has a comfortable gap to place 16 with 10 points. They can actually be satisfied with that. But if I take a closer look, I can see that their last win were 6 matchdays ago against Köln. After that they only managed a drew one time and lost four times. But Franktfurt's performance in recent games has also been very mixed and there is no clear trend to be seen.
If Bremen will lose today and Mainz will win tomorrow things could get exciting again. Especially because many teams in the danger zone are playing against each other this weekend.
Looking at both Frankfurt and Werder Bremen, they are both not in good form currently, so it will be hard to say this is the particular team that will win the game at the end of today's match, and as you said, each of these teams is not in the position that they will be in, so worry so much about aiming for the upper position. At this moment, Frankfurt is in sixth place in the table, and Leipzig is ahead of them with nine points. So I don't think Frankfurt will be that motivated to take the position from Leipzig due to the point gap between them, and for Werder Bremen, they are not in the relegation zone, so they may not be worried that they want to improve to be out of the relegation zone, so I don't even think their ball will be that interesting, but if I should look at home advantage, I will say the favourite team to win today's match should be Frankfurt.
Actually you're wrong, there are still 7 weeks to go which mean the maximum points they could earn up to 21. If Bayern Munich win at least 5 matches and Leverkusen lose streaks, Bayern Munich will become the winner.
I don't think it is possible for Leverkusen to lose almost all their remaining matches at this moment with their current form. I am aware that football is full of surprises, but I don't think it will happen that Bayern Munich will have the opportunity to win the Bundesliga trophy this season. It is very clear that Leverkusen will surely be the winner of this season's Bundesliga trophy. It is even possible that Leverkusen will win the Bundesliga unbeaten; it is just a few matches that remain before they will crown the season's Bundesliga champion.
