Leeds would rather hold on to Viduka but supporters now have reservations about the player's commitment.
There was widespread anger among fans when it emerged Harry Kewell had played for six months last season with his heart set on a move to Liverpool.
Now that Viduka's desire to leave has become common knowledge, and with Reid acknowledging a training ground bust-up, the striker could be omitted from tomorrow's friendly at Hull City and Michael Bridges could partner Alan Smith up-front, with the Aussie on the bench.
However, D'Amico was quick to play down suggestions Viduka is no longer committed to The Whites.
"Mark is very professional and he has a contract with Leeds," said D'Amico. "He has a lot of respect for the fans, for the club and himself and he never says stupid things in public.
"Obviously it depends on what opportunities there are in the market. If I can find some good options for Leeds and the player, we can consider them." If Viduka puts a transfer request in writing, he will forfeit over £1m in loyalty bonuses and Reid said: "We have heard nothing official about Mark wanting to leave."
A report in today’s Sun suggests Leeds are now willing to sell for £10m - despite insisting he was going nowhere on Wednesday.
