Official Fantasy Bundesliga Managers take note: bundesliga.com is on hand to provide likely line-ups as well as injury and suspension news ahead of Matchday 14.
Injury problems could force Köln to start in a 5-3-2 formation against Dortmund. Midfielder Marco Höger is back after a knee injury, but Simon Zoller (shoulder) and Anthony Modeste (knee) both missed training on Tuesday due to minor complaints, and will have to undergo late fitness tests to see if they are able to play. It would be a major blow for Peter Stöger to lose top goalscorer Modeste, who has netted 12 Bundesliga goals for the Billy Goats this season.
