DORTMUND, Germany (Reuters) - Borussia Dortmund's performances are not all negative despite two straight league losses, but the players must boost their confidence with wins, said coach Niko Kovac ahead of Wednesday's Champions League playoff second leg against Sporting.
Dortmund lost 2-0 to VfL Bochum on Saturday, their second defeat in a row in the league under Kovac that meant the Ruhr valley club dropped to 11th place, only days after last week's 3-0 first leg playoff win over Sporting in Lisbon.
