On the other hand Stuttgart are trying to secure their Champions League spot. They are actually 6 points away from the fifth position but there is nothing guaranteed while there are four more weeks. After that Werder Bremen loss I expect them to play better this time. I wouldn't bet on Stuttgart's double chance though but both teams to score looks quite nice @1.58.
If we look at the statistics between the two, we can see that Leverkusen still has the upper hand by never losing against Stuttgart. Apart from that, this time it is Leverkusen's turn to host Stuttgart in the second round of the Bundesliga so that it will be easier for Leverkusen to maintain their unbeaten record and will continue to increase their numbers.
I think there is no strong reason for Stuttgart to win and even if it is possible they can only hold Leverkusen to a draw in this away match. Such consistent performances are always an interesting thing from Leverkusen and maybe even if Leverkusen are behind they will still be able to turn things around in the 90+ minute and that is nothing new that we have seen so far with Xabi Alonso. BTTS betting allows us to avoid greater risks and what is clear is that both teams will steal each other's lead through goals.
In the last match of Stuttgart, they have lost against Werder Bremen. and they will have to face Bayern Munich and Leverkusen in the next two matches in the Bundesliga. so I think it is going to be a very hard thing for them to win in those two matches. I still do not think they will actually fall down to the fifth position. But I think they will probably not stay in the third position if they lose both of those matches. Leipzig Is performing well so probably there is a chance for them to get ahead of Stuttgart.
But the performance of Dortmund is not good at this moment. and I do not think they will actually be able to finish in the top four position. what I am trying to say is that the performance of Stuttgart is definitely not good right now but at the same time they are probably not going to finish under the top four positions as well. but I guess finishing in the third position is always better than finishing in the 4th. either way, they are going to play in the Champions League though. unless they actually somehow fall down to the fifth position by the way. But I also think that is highly unlikely to happen.
