Former West Ham United midfielder Stewart Robson believes that the club could suffer relegation at the end of the Premier League season.
"If West Ham's performances don't improve then they have every chance of going down," Robson told talkSPORT.
"There is a real concern over West Ham's position in the Premier League. I looked at their back four against Crystal Palace and the two centre-halves are not good enough."
The Hammers will face Liverpool at the weekend.
