FC Koln and Borussia Monchengladbach remain unbeaten in the Bundesliga this season having played out a goalless draw at the RheinEnergieStadion.
The hosts had the game's best chance on 17 minutes when Pawel Olkowski latched on to a through-ball, but he fired wide of the target when one on one with Yann Sommer.
Max Kruse outjumped his marker inside the box as the Foals went in search of an opener in the second half, only to see his header fly narrowly wide of goal.
Neither side were able to find a way through in what was a game of few chances, however, ensuring that they remain locked on six points in the league table.
