Köln's results are inconsistent, sitting in the middle of the league table. They've alternated wins and losses in recent matches, but regularly score even against strong opponents. Their attack is capable of creating chances, as evidenced by the 2-2 draw with Heidenheim.
Wolfsburg is struggling, sitting in the relegation zone. Their defense is weak (41 goals conceded), but they often score. Their head-to-head matches this season have ended with a high-scoring 3-3 draw.
Given both teams' inconsistent defense and their motivation to fight for points, a mutually beneficial outcome is highly likely.
