Istanbul: Borussia Dortmund are looking to brush off their nightmarish Bundesliga form when the Group D leaders protect their perfect , record at Turkish giants Galatasaray today.
Dortmund coach Jurgen Klopp described his side's 3-0 win at Anderlecht earlier this month as "perfect", but things are far from rosy now for Borussia after three straight Bundesliga defeats.
With just a point from their first two European games, Galatasaray are third in the group and face Dortmund with the Germans low on confidence despite topping the Champions League group.
The 2013 Champions League finalists have plummeted to 14th in the Bundesliga table — their worst league start for 27 years.
Klopp admitted to feeling "helpless" in the wake of Saturday's 1-2 defeat at Cologne, their first defeat in the city for more than a decade, to leave them with just a point from their last five league games. "We have to correct our mistakes now, not tomorrow or the day after," fumed Klopp. "We need to get ourselves out of this rut and no one will do it for us."
Having beaten Arsenal 2-0 in their opening game, Klopp's side have yet to concede a goal in the competition and have been boosted by the return to fitness of three key players. They have Germany midfielders Marco Reus and Ilkay Gundogan, as well as Henrikh Mkhitaryan back after injuries.
Reus managed more shots on goal than the entire Cologne team combined and finishing is a factor for Dortmund in Turkey. There was some bad news for Klopp from Cologne as defender Erik Durm, who was injured in the warm-up, also misses the trip to Istanbul with a thigh strain and his place at left-back is likely to go to Kevin Grosskreutz.
Galatasaray lost 1-4 at Arsenal three weeks ago and need a result at home against Dortmund to keep their knock-out stage hopes alive.
