The former Reading and Cork City front man has been a target for several clubs and may find himself on the way out
Doyle, 29, was heavily linked with Scottish Premier League champions Celtic in January of this year, while it is believed that English Premier League clubs West Brom and Everton have also been monitoring the availability of the Republic of Ireland international.
"Agents and vultures will be looking at our players and thinking, ‘who can we pick out of there?’," said Wolves boss Dean Saunders.
"It happened last summer when they took all the best players out of Wolves after they were relegated from the Premier League.
"It will probably happen again if we don't stay in the Championship. People will pick who they think are the best players and sometimes you won't be able to do anything about it."
Meanwhile, Giovanni Trapattoni has been dealt an injury blow ahead of forthcoming international fixtures as Aston Villa defender Ciaran Clark has suffered a setback which will rule him out of his side's Premier League clash with Norwich at the weekend.
"He damaged the bottom of his foot in training and will again be out of action at Norwich," said Villa boss Paul Lambert.
Elsewhere, Trapattoni received a boost as West Bromich Albion striker Shane Long has been deemed fit by manager Steve Clarke, who praised the former Cork City player's "top" performances.
"I don't think Shane is injured at the moment," said Clarke. "Shane is in a good place. I think his performance last week was top.
"Players now, you have to manage, you have to look after them all the time. It is a long physical season and there will be knocks."
