Hailing from a town with a population of around just 13,000 people, Elversberg earned promotion to the Bundesliga for the first time in the club's history last season.

While not much was expected of them, they surprised a lot of people - including Leverkusen - by bursting out of the blocks full of belief and purpose on Saturday.

Elversberg raced into a 2-0 lead inside the opening nine minutes through Lukas Petkov and Cole Campbell, then added a third via David Mokwa right after half-time.

Leverkusen fought back late with goals from Patrik Schick (77’) and Christian Kofane (90+1’), but the newcomers held on for a famous win.

Serhou Guirassy opened the scoring inside the opening 10 minutes, with Giannis Konstantelias having shot deflected in off Sebastiaan Bornauw for an own goal just before half-time to put them in a commanding position.

However, Union Berlin showed a lot of heart to fight back through goals from Leopold Querfeld (79’) and Tim Skarke (90+2’) to rescue a point in a high-scoring draw.
