It hurts a lot – Arnautovic concerned over knee injury

West Ham ended its losing streak at Everton on Sunday, but it came at a cost as Marko Arnautovic suffered an injury setback.

West Ham's Marko Arnautovic

Marko Arnautovic was unable to reassure West Ham fans about the knee injury he sustained in Sunday's 3-1 win at Everton, acknowledging he is in a lot of pain.

Arnautovic played a vital role as the Hammers picked up its first points of the season at Goodison Park, setting up Andriy Yarmolenko for the opener before scoring West Ham's third himself. 

But, the Austria international had to be withdrawn shortly afterwards, having gone to ground clutching his left knee. Although he was able to walk off, Arnautovic was not able to downplay the injury.

"I don't know, we need to check now. It's not my calf, it's my knee. It hurts a lot. We will need to check this week," he told Sky Sports .

West Ham's initial front three of Arnautovic, Yarmolenko and Felipe Anderson impressed, causing Everton no end of problems.

But, Arnautovic was quick to highlight the collective display of West Ham's midfield, with Declan Rice and Pedro Obiang particularly effective.

"It's not about us three [the front three]. It starts from the goalkeeper [Lukasz Fabianski] and everyone has done an unbelievable job," the forward said.

"The midfield was everywhere and then it's down to us to score goals and win games. Credit to Yarmolenko for his goals."

From Everton's perspective, however, Marco Silva feels that his side was guilty of mistakes which made things easy for its visitor.

In the end, Silva was left ruing Everton being taught "a lesson". "We weren't good enough to win the match. We started well, until the first mistake we made," said the Toffees boss.

"We prepared for the situations when the opponent was on the ball, with Arnautovic, we prepared, but at that moment we did not do what we needed to do."

"We conceded too many chances defensively, but we created the chances to score, a good number of clear chances. It’s a big lesson for us to learn fast. It's the Premier League, it's the way. Of course you have to improve to see what we did wrong."
