Borussia Dortmund will be missing captain Emre Can and midfielder Carney Chukwuemeka when they play Barcelona in the Champions League quarter-final second leg. Can's absence is due to muscular issues, as confirmed by head coach Niko Kovac, while Chukwuemeka's reason for missing the match is unclear, possibly due to his recurrent injuries since joining in the winter transfer window. Marcel Sabitzer and Nico Schlotterbeck are also unavailable for the team. Dortmund faces a challenging task at Signal Iduna Park, needing to overcome a 4-0 deficit from the first leg against Barcelona.
