Crystal Palace manager Neil Warnock admits co-chairman Steve Parish is also working as part-time director of football.
Former sporting director Iain Moody has not been replaced since quitting in August.
Warnock said: "The chairman is doing Iain Moody's role at the moment. I've given him the names. He has spoken to the agents and clubs and he has made the offers. Every time I go into his office he is looking at players on his computer. He has taken more on his shoulders than he should do.
"The more you take off the manager the better. You have so much to do as a Premier League manager, so many commitments.
"The structure of the club will change next summer, if not before. Steve is looking for that now to take a bit of pressure off him."
