Veteran manager David Moyes and his West Ham side are furious at Premier League scheduling.
The Hammers are not best pleased that a game has been scheduled against Luton Town on transfer deadline day.
The Hammers are working hard to get deals done for players to come into the club.
They also want to sell the likes of Pablo Fornals, Danny Ings, Maxwel Cornet and Ben Johnson.
Moyes said yesterday to reporters: I don't think I will be taking a sub off and saying, 'Hey get yourself stripped and showered, you're on your way somewhere else!'
We could find we have players who maybe could be outgoings and if that is the case, it does make it a difficult day.
What can we do about it? I trust the people behind the scenes to do what they have to do."
He added: We will be right in it until the last minute. But, being on deadline day, it makes it really difficult for myself and everybody else to be involved. We have a game to prepare for.
Sky rely a lot on deadline day. You lot live by it. It is unfair we are playing on deadline day. I think there has only ever been a handful of games played on the summer's deadline day and we are one of them."
