Ten-man Bielefeld stuns RB Leipzig
Janni Serra and Masaya Okugawa scored second-half goals as the 10 men of relegation-threatened Arminia Bielefeld celebrated a shock 2-0 win away to RB Leipzig in the Bundesliga on Sunday (AEDT).
Leipzig had barely got started when an injury to Emil Forsberg forced Domenico Tedesco into a midfield reshuffle. United States captain Tyler Adams was his replacement, but not even his direct running and industry could ruffle the feathers of a dogged Bielefeld unit.
Christopher Nkunku headed over from a Dominik Szoboszlai cross with the hosts' only real attempt on goal, with Arminia stand-in goalkeeper Stefano Kapino untested in a hard-fought first half.
Opposite number Peter Gulacsi was beaten on the stroke of half-time, but Okugawa's goal was ruled out for an offside against Patrick Wimmer in the build-up.
Bielefeld's next effort did stand, however. Serra instigated a lightning counter with a pass out wide to Florian Krüger, before continuing his run and sliding in to convert after Gulacsi had denied Wimmer at close quarters.
Leipzig was given a boost when Arminia substitute Fabian Klos was shown his marching orders upon a video assistant referee (VAR) review, after a dangerous tackle on Willi Orban, but the visitors hadn't read the script.
A mistake by Amadou Haidara gifted possession to Krüger, who picked out Okugawa for a clinical finish from 15 yards.\
Bielefeld battoned down the hatches to end the year only two points adrift of outright safety, with Leipzig six points off the top-four in ninth.
