West Ham showed their resilience and character as they came from behind to beat AZ Alkmaar 2-1 in the first leg of their Europa Conference League semi-final at the London Stadium.
The Dutch side had taken a shock lead in the 28th minute when Tijani Reijnders latched onto a loose ball and drilled a low shot past Alphonso Areola from the edge of the box.
But West Ham did not give up and equalised in the 54th minute when Said Benrahma converted a penalty after he was fouled by Timo Letschert in the area.
The hosts then completed their turnaround in the 69th minute when Michail Antonio headed home a cross from Pablo Fornals to score his 15th goal of the season.
West Ham will travel to Holland next week with a slender advantage as they look to reach their first European final since 1976.
