Robert Lewandowski is confident that his former club Borussia Dortmund will bounce back after a slow start to the Bundesliga season.
Dortmund have failed to find their stride in the post-Lewandowski era following the striker's summer switch to Bayern Munich, as last season's runners-up sit 13th in the table - 10 points adrift of the Bavarians.
Despite the sizeable gap, the Polish hitman is convinced that Jurgen Klopp's side will recover from their early-season woes and challenge Bayern for the title once more.
"They have very bad luck with injured players at the moment," he told Bild. "But they are still a tough competitor for us, I'm sure."
The 26-year-old joined Bayern on a Bosman in the summer after netting 103 times in a four-year spell at Signal Iduna Park.
