A few weeks ago, Dortmund trailed Bayern by only three points and appeared well placed to reach the last 16 of the UEFA Champions League after a 2-0 play-off round first-leg victory over Atalanta.
However, a 2-2 draw with RB Leipzig followed by a 4-1 defeat against the Serie A side in the second leg saw them knocked off their stride Despite pushing the Bavarians all the way in Der Klassiker three days later, a 3-2 reverse left them 11 points adrift of the league leaders with just 30 still on offer.
