Sunderland boss Chris Coleman insists Didier Ndong will only leave for the right price.
Watford and West Ham are rivals to sign the want-away £14million Sunderland midfielder.
Coleman said: “What do we get out of a loan deal as a club?
“A loan deal where he would need to play 75 per cent of the games and there's a fee at the end of it? He will probably play 73 per cent.
“Didier would like to leave, he sees his future elsewhere, but we have to do what's best for us. There will be no loan deal unless it suits us financially."
