David Moyes saluted a 'massive' performance from West Ham after they stunned Sevilla to reach the quarter-finals of the Europa League.
Andriy Yarmolenko climbed off the bench to sink the LaLiga side as the Hammers prolonged their European adventure with a dramatic extra-time win.
West Ham, debutants in the knockout stage of the Europa League, became the first English team to beat the six-time winners in the tournament at a raucous London Stadium.
Trailing 1-0 from the first leg, Tomas Soucek headed West Ham level in the first half and, on a genuine European glory night reminiscent of Upton Park in its heyday, Yarmolenko fired the Hammers to a 2-1 aggregate victory and into a historic quarter-final.
