Bolton Wanderers boss Sammy Lee has told Nicolas Anelka and El Hadji Diouf they must stay.
Both may have moved on by the time the transfer window closes next week.
But Lee said: "They need to honour their commitment to this club. While they are still here they need to be committed to what we are trying to achieve.
"They need to give it their best shot to get us out of the position we are in.
"I have seen nothing to convince me they are going, though I want to work with people who are committed to this club."
