West Ham United forward Marko Arnautovic has revealed that the knee injury he suffered in Sunday's 3-1 win over Everton 'hurts a lot'.

Arnautovic scored the all-important third goal before being hauled off.

"I don't know, we need to check now," he told Sky Sports.

"It's not my calf, it's my knee. It hurts a lot. We will need to check this week."
