Marek Hamsik is out of the Napoli team for tonight's match against Borussia Dortmund, but the home side have concerns of their own in defence.
Borussia Dortmund face a Napoli side without Marek Hamsik tonight in the Champions League.
Swiss international Blerim Dzemaili comes into a two-man defensive midfield for the visitors, who have Gonzalo Higuain as a lone frontman.
However, there are also problems for Dortmund. Defender Manuel Friedrich is not registered to play, so therefore Sven Bender becomes a centre-back for the night and partners Sokratis Papastathopoulos.
Sebastian Kehl is in midfield, with Jakub Blaszczykowski on the right hand side.
Borussia Dortmund:Weidenfeller; Grosskreutz, Sokratis, Bender, Durm; Sahin, Kehl; Blaszczykowski, Mkhitaryan, Reus; Lewandowski
Napoli:Reina; Maggio, Fernandez, Albiol, Armero; Dzemaili, Behrami; Callejon, Pandev, Mertens; Higuain
