Borussia Dortmund thrashed second-division Holstein Kiel 5-0 on Saturday in their German Cup semi-final even with top-scorer Erling Braut Haaland sidelined. Haaland, suffering from a thigh injury, watched from the stands at Signal Iduna Park as Giovanni Reyna started the rout with the first two goals to help put Dortmund in the final at Berlin's Olympic Stadium on May 13. Dortmund will face RB Leipzig, who needed Emil Forsberg's 121st-minute winner at the end of extra-time to seal a dramatic 2-1 win at Werder Bremen on Friday in the other semi-final.
