bundesliga.com looks ahead to Matchday 10's intriguing tussle at the RheinEnergieStadion...
One of just two sides still to pick up three points in 2014/15, Freiburg could be bottom of the table by the time this one gets underway. Christian Streich's side are already seven points worse off then mid-table Köln and are in very real danger of repeating last year's ten-match winless start to the season.
Peter Stöger is still without the services of loanee defender Tomas Kalas and experienced Bundesliga striker Patrick Helmes (both hip). Influential midfielder (pictured) has also been ruled out with a muscle complaint, meaning Slawomir Peszko could be in line for a start.
(pictured) faces a spell on the sidelines after damaging knee ligaments in last weekend's defeat to FC Augsburg. Stefan Mitrovic is expected to slot in alongside Marc Torrejon at the heart of the back four, while Sascha Riether and Sebastian Freis are also in contention after starting the midweek DFB Cup win over TSV 1860 Munich.
Anthony Ujah stepped off the bench to score the only goal of the game in Matchday 9's narrow win at SV Werder Bremen. The Nigerian frontman has netted twice this season and will certainly feel he has enough in the locker to change the fortunes of the Bundesliga's third-lowest scoring outfit so far this term.
Freiburg are fourth from bottom in the goals-for chart, with injury restricting Swiss international to just six league starts. The 23-year-old is still yet to score in the league this season, but travels to Cologne fresh on the back of bagging a Cup hat-trick at the Allianz Arena.
Peter Stöger, Köln head coach: "It won't be an easy game. [Freiburg] are on the same level as us."
Christian Streich, Freiburg head coach: "[Mehmedi] didn't play well at Augsburg, but he's needed these last few games. He's fit now and we're really happy for him."
The Billy Goats made it three wins from their last three in all competitions with a over MSV Duisburg in the DFB Cup. Freiburg also progressed to the third round thanks to a comfortable in Munich, despite amassing just five points from nine league outings in 2014/15.
Köln recorded only their second win in six league games against Freiburg with a resounding 4-0 home win back in December 2011. Freiburg returned the favour with a 4-1 success of their own later that season, but remain without a win on Cologne soil in three attempts (D1, L2).
Köln: Horn - Olkowski, Mavraj, Wimmer, Hector - M. Lehmann - Peszko, Vogt, D. Halfar, Svento - Ujah
Freiburg: Bürki - Sorg, Torrejon, Mitrovic, C. Günter - Schuster, Darida - Schmid, Klaus - Freis, Mehmedi
