West Ham are against radical plans by Liverpool and Manchester United to reform the English football pyramid, according to a club source.
The Project Big Picture proposals have been put together by Liverpool owner John Henry and United co-chairman Joel Glazer.
Everton, Southampton and West Ham would be granted special status in the plans, along with the so-called 'big six'.
However, a Hammers insider has told BBC Sport they are "very much against" it.
It is understood the club were unaware of the proposals, even though they were named in them - and were shocked when they emerged into the public domain on Sunday.
