Mario Pasalic's first-half strike had looked set to settle a contest in Lisbon that will be remembered for a series of first-half misses from Neymar, the worst of which came when through on goal in the third minute.

Thomas Tuchel's side dominated large spells but looked short of sharpness after playing few games in the past five months, even following Kylian Mbappe's introduction from the bench after he shook off an ankle injury.

However, Marquinhos prodded home a fortuitous equaliser in the 90th minute before Neymar and Mbappe combined to set up Eric Maxim Choupo-Moting to become the unlikely hero and break Atalanta hearts.
