Rampant Dortmund will put stuttering Real to the test

European champion Real Madrid heads to rampaging Borussia Dortmund for its Champions League Group F game on Tuesday in a frazzled state with its buoyant start to the season having been punctured by successive La Liga draws.

Real gave away a late equalizer to draw 2-2 at Las Palmas on Saturday, after its joint-record 16-game winning streak in La Liga was halted by Wednesday's 1-1 home stalemate against Villarreal, which saw its lead at the top cut to a point.

Dortmund, meanwhile, has been on a sizzling run since losing to RB Leipzig on Sept 10, scoring 20 goals in four straight wins against Legia Warsaw in the Champions League and Darmstadt, Wolfsburg and Freiburg in the Bundesliga.
