Atalanta striker, Gianluca Scamacca, scored twice as they thrashed Liverpool 3-0 in the first leg of their Europa League quarter-final tie.
Scamacca peeled off Ibrahima Konate and Virgil van Dijk centrally, applying a cool first-time finish to Davide Zappacosta’s low cross.
He scored his second on the hour mark side-footing Charles De Ketelaere’s delivery beyond Kelleher.
This came minutes after Klopp had introduced Mo Salah, Dominik Szoboszlai and Andy Robertson from the bench.
The collapse was complete in the 84th minute when Szoboszlai lost the ball softly in midfield, freeing Ederson, before Pasalic atoned for his earlier miss by tapping into an empty net from Kelleher’s poor parry.
Jonas Hofmann and Victor Boniface came off the bench to unlock West Ham and earn Bayer Leverkusen a late 2-0 victory in the first leg of their Europa League quarter-final.
