Former West Ham United midfielder Stewart Robson believes that the club could suffer relegation at the end of the Premier League season.
The Hammers currently sit 15th in the table following last night's 1-0 defeat to Crystal Palace at Selhurst Park.
Following their performance, Robson has criticised defenders James Tomkins and James Collins, stating that they are "not good enough".
"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.
