Hodgson has yet to taste victory in his four matches in charge as he picks up the pieces of Sanchez's disastrous spell at the club.
The limitations of the squad assembled by Sanchez during last summer's ill-advised £25million spending spree have been repeatedly exposed, leaving Fulham five points adrift of safety.
"It is not appropriate to comment on what I thought the previous manager was doing," he said.
"Each manager tries to put together a squad he believes in, that will work in the way he wants them it work and that will adhere to the philosophy he sets down.
"When a new manager comes in certain players will be what he wants and certain won't.
"I have no criticism or judgement on what has gone on before. Instead, it is up to me to work as hard as I can with the players who are contracted to the club.
"But more importantly at the moment I must try to use this transfer window to bring in some players who will help me make the team even better."
