David Moyes has warned his West Ham players are staring at bleak futures if their Premier League slide continues.

West Ham suffered a second successive 4-1 defeat at Swansea on Saturday and sit only three points above the relegation zone after one win in six games.

"They have been told this was miles and miles away from where I'm going - or they are going," said manager Moyes, whose own West Ham future beyond this season has been a topic of discussion.

"If they are going to play like that, then there'll be none of us here.

"The players need to show a wee bit, but I think they are good enough to do that.

"But they definitely all need to up their levels, because this wouldn't be good enough to win the games we've got coming up."

West Ham - who have 30 points from 29 games - are only above Crystal Palace and West Brom in the Premier League form table.

They were blown away at Swansea with an injury-hit defence destroyed by the pace, power and movement of the Ayew brothers, former Hammers striker Andre and his younger sibling Jordan.

West Ham have the joint-worst defensive record with Stoke, conceding 54 goals, and successive home games against Burnley and Southampton have now taken on added importance.

"Those games could define our season," Moyes said.

"We are down to nine games now. Before I was thinking, a point a game will get you to about 40 points.

"That's always been the old-fashioned figure (for safety), but we are now having to do more than that.

"I'd like the message to be that we'll be fine, but the truth of the matter is we're not.

"I want us to be positive and look forward, but we have to stop conceding goals."
