Michail Antonio opened the scoring for West Ham when he pounced on a wayward back pass and slotted into an empty net for 1-0, putting his side in total control of the encounter.

The Hammers never looked like giving up their lead and midfield star Declan Rice soon gave supporters more to celebrate, bursting through the middle and scoring a fantastic solo goal.

Following West Ham's memorable night at the Stadion Maksimir, the club dropped a four-word message for fans on Twitter, simply reading: "What a night, Hammers!".

In response, Irons supporters relived the excitement of their first Europa League victory of the group stage as they put their stamp on the competition already.
