Kostic scrambled to match him, but the Frankfurt speedster powered forward, eating up the turf with long, relentless strides.
One touch to set, another to burst past Kostic's desperate reach, and suddenly he was thundering down the right channel with the defense scrambling.
"Knauff is away! This is a three-on-three break for Frankfurt!"
Approaching the box, Knauff dropped his shoulder and swept a low, driven cross across the face of goal.
The ball skidded wickedly on the slick grass, bending perfectly into the path of Ekitike, who ghosted between Djiku and Bonucci.
Ekitike met it first time with a side-footed sweep, guiding the ball with the calm precision of a marksman.
It skimmed off the turf and nestled into the bottom-left corner beyond Egribayat's despairing dive.
GOOOOOAAAAL!!!
The away section detonated in uncontainable celebration, banners whipping and smoke rising as their chants drowned the stunned silence of the Kadıköy faithful.
