Hertha will go into the match having secured a surprising three-goal to two victory over Borussia Dortmund just before the winter break, it means they find themselves sitting in 11th place four points above the relegation places.
Hertha know that a victory on Sunday would put them just one point behind Köln as well as just three points behind Eintracht Frankfurt in the final European place providing results also go their way. However, if they lose there is a possibility that they could move down to as low as 15th place.
Like Hertha Köln also went into the winter break having won by one goal to nil against VFB Stuttgart. The result means that ahead of the match they currently sit in 8th place.
Köln know that a victory on Sunday will greatly improve their chances of playing European football next season as they are only two points behind Eintracht Frankfurt in sixth and three behind Bayer Leverkusen in fourth place.
Hertha head coach Tayfun Korkut has only got several injuries goalkeeper Rune Jarstein is definitely out of contention to play on Sunday while defender Martin Plattenhardt and striker Stevan Jovetic are both doubtful due to injuries they have picked up recently.
Meanwhile, Köln head coach Steffen Baumgart has got several injuries albeit not to key players. Matthias Koobing, Denis Strauch are both out due to injury while Ellyes Skhiri is unavailable due to him competing in the African Cup Of Nations.
Hertha Berlin: Schwolow, Pekarik, Stark, Torunarigha, Mittelstädt Richter, Darida, Serdar, Ekkelenkamp, Selke, Maolida
FC Koln: Schwäbe, Schmitz, Kilian, Hübers, Hector, Özcan, Ljubicic, Duda, Kainz, Andersson, Modeste
Players to watch
With striker Stevan Jovetic having continuous problems with injury, Hertha have needed someone to step up. That player is Marco Richter.
Richter will come into the match feeling very confident after managing to get a brace against Dortmund before the winter break and with him having scored five goals already this season he will be looking for more.
In terms of key players for Koln the main player who is absolutely crucial is Anthony Modeste who has been by far their best player.
Modeste is miles clear of any other player in terms of goals with 11 goals in 17 matches. No other player at the club has scored more than five goals so far this season, meaning Modeste will be absolutely vital on Sunday.
