RB Leipzig host Borussia Dortmund on Saturday with possible Champions League qualification at stake in what has become one of the Bundesliga's bitterest rivalries in recent years. Fourth-placed Leipzig sit two points clear of Dortmund in fifth, with only the top four clubs guaranteed Champions League football next season -- although Germany may snare a fifth spot in the new UEFA qualification system thanks to strong European performances. The rivalry between the sides has been fierce ever since Leipzig were first promoted in 2016.
