Two goals from Marko Arnautovic – including a stunning volley – and a first West Ham goal for Joao Mario earned the Hammers a deserved 3-0 win against Southampton.
All three of the Hammers’ finishes came in a blistering first half for the home side, with Mario powering home a terrific shot from the edge of the box into the roof of the net.
On 17 minutes Arnautovic got his first, calmly tucking away from close range after his initial header was well saved.
The attacker saved the best goal for the end of the first period, excellently volleying into the net after a magical cross from the returning Arthur Masuaku.
