Champions League Group D heavyweights Dortmund and Real Madrid square off on Wednesday in the first of a two-leg series that could settle which sides advance from the so-called "Group of Death."
Late dramatics saw Real claim three points from Manchester City in their first match of the group, but the Spanish champions silenced any doubters with an emphatic 4-1 win away to Ajax earlier in October.
Dortmund similarly had a late winner to thank for their first three points, but stumbled in the second matchday as they outplayed Manchester City, but only managed to take a draw following a late equalizer. They could leapfrog their opponents on Wednesday with a win, but have it all to do, as the visitors will be keen to open a potential five-point lead in Group D.
