West Ham chairman Eggert Magnusson has criticised former manager Alan Pardew and claimed there had been a growing rift in the Upton Park dressing room.
Pardew was sacked as Hammers boss in December after a series of bad results and was replaced days later by Alan Curbishley who left The Valley last summer after almost 15 years in charge of Charlton.
The pair will come face to face next weekend with both sides desperate for points in a relegation battle at The Valley.
Magnusson told the News of the World: 'There was no purpose to talk about it publicly at the time.
'But the key factor was something was just not right in the dressing room.
'Tension had been building between the players and the manager for a while.
'There was a cancer we had to cut off.'
