West Ham United boss Sam Allardyce knows he needs a win soon to keep his job.

Before their thrashing at Manchester City, Allardyce received the backing of the club's hierarchy this week but he accepts performances must improve.

He said: "You cannot keep losing football matches, that is for sure, as a manager.

"You cannot think it will be allowed to continue. I don't want it to continue that is for sure.

"We know the reasons why but in the end even those reasons won't save you.

"We have to get those (injured) players back as quick as we can and we have got to not lose confidence in our own ability and get out of this hole we are in at the moment."
