What a way to kick off Matchday 23: Friday evening under floodlights, a sell-out crowd at Signal Iduna Park, second-placed Borussia Dortmund against RB Leipzig, four points behind them in fourth. The hosts on a nine-game winning streak across the board, the visitors with more points under their belt than any other team in the division since Marco Rose took over last September. The self-same Rose who steered Dortmund to runners-up spot last season, now returning to his former stomping ground by way of an added twist.
