Oleksandr Zinchenko was filmed celebrating Bukayo Saka's winning goal as Arsenal defeated Liverpool 3-2 on Sunday.
With the score at 2-2, 21-year-old Saka stepped up to put his side ahead from the penalty spot in the 76th minute after Thiago had clipped Gabriel Jesus in the area.
The forward slotted low past Allison to score what was ultimately the winning goal, and, in a video shared on social media, the injured Gunners defender can be seen cheering from the stands as the ball hits the back of the net.
