Tensions were high at the London Stadium as West Ham attempted to overturn a 2-0 deficit from the first leg in Germany.
The hosts got off to a dream start when some smart work by the returning Jarrod Bowen set Antonio up to head past goalkeeper Matej Kovar and send the home crowd into pandemonium.
West Ham would need to hand their opponents a first defeat of the season to reach the semi-finals, however, after Alonso’s outfit stormed the Bundesliga title and were unbeaten in all competitions before their trip to London.
