It is very likely that both Bayern Munich and Bayer Leverkusen are going to win their away matches and for Bayern Munich this should be easier than for Leverkusen. I think Wolfsburg isn't a very good team, but also not a bad team, which means that they can resist some pressure for some time. It is still weird that Cologne is sticking to their coach and haven't done anything about it yet. But there has been some negative trend since two seasons ago when they finished 7th. In my opinion at the end of the season they could be in the relegation zone this season.
I only believe in Bayern Munich, for Bayer Leverkusen, even though the bookies favor them, there's a tendency that they will also get a draw in this match. Bayer Leverkusen's winning streak isn't an ordinary thing, it is not natural that they will get positive results continuously, that's the reason I'm not sure that Bayer Leverkusen can win easily against Werder Bremen.
Regarding Koln, they're currently in the relegation zone with Union Berlin, it's not impossible that they will be relegated at the end of the season considering their current performance.
I noticed a confused Wolfsburg with Werder Bremen, yes the game is Wolfsburg vs. Bayer Leverkusen. But this doesn't make much of a difference and I agree that there is some potential for this game to end in a draw. It feels like Leverkusen's run has to come to an end whether we want it or not
If they continue they, they finally deserve that Bayern Munich fails in a game so they can extend their lead, but Bayern Munich isn't making mistakes in the Bundesliga and if they do, they simply score more goals. The offense is what works like a charm for them.
