West Ham boss Slaven Bilic insists Diafra Sakho will miss West Ham's FA Cup quarter-final replay against Manchester United through injury and not as a disciplinary measure.

Sakho withdrew from Saturday's Premier League meeting against Arsenal, citing a knee injury after an early-morning message on social network Snapchat which read: "When I'm hated I don't give a f***, I do everything to be more hated."

"The situation is very simple," he said.

"He reported an injury after training on Friday and then he was not in the squad, yesterday he had a scan and it reported a little bit of a problem.

"He is out for hopefully one week, not more than that, but for this week he is definitely out and hopefully he will be back on Monday."
