West Ham remain well placed to make back-to-back European semi-finals despite seeing their 100 per cent winning run in the Europa Conference League ended by Gent.
The Hammers looked on course to make it 11 wins out of 11 in Europe this season when Danny Ings tapped home after the hosts were caught out by a quickly taken throw-in.
David Moyes' side, Europa League semi-finalists last season, had to soak up waves of Gent pressure in Belgium and Hugo Cuypers equalised after a clever touch and finish.
Gent piled forward in search of a winner to take into next week's return leg, with Gift Orban - who scored a hat-trick in 205 seconds in the last round - hitting the bar with a wonderful 82nd-minute acrobatic attempt.
