With a little under 25 minutes remaining, Liverpool needed three goals to overcome Borussia Dortmund and reach the semi-finals of the Europa League.

The first leg of this last-eight tie had ended 1-1, but Dortmund's electric start to this game appeared to extinguish any hopes Jürgen Klopp had of eliminating his former club.

Anfield was left stunned when Henrikh Mkhitaryan and Pierre-Emerick Aubameyang put BVB 2-0 up inside the opening 10 minutes.

A punch-drunk Liverpool managed to stagger their way to half-time having suffered no further damage, and Divock Origi gave the home fans a glimmer of hope with a cool finish early in the second period.

No sooner had the Reds reduced the deficit, Marco Reus made it 3-1 to Dortmund on the night. That, it seemed, was that.

But when Philippe Coutinho pulled one back, hope crept back into the Anfield crowd. When Mamadou Sakho drew Liverpool level on the night with 13 minutes left, that hope turned into belief.

And when Dejan Lovren towered above the Dortmund backline to plant a firm header into the Kop-end net in injury time, that belief turned into bedlam.
