Moses has broken off from contract talks with the Latics and Finnegan has revealed that the Nigerian international is looking for a summer move.
Finnegan is quoted in the Sun newspaper: "I think what Wigan have done is tremendous and shows it was the right place for him to go after Palace. But now I think Victor is ready for the next step.
"He still has lots of improving to do in terms of scoring goals more regularly.
"But I think that would come if he was surrounded by better players.
"That's what he wants and is why he won't be extending his contract. I can't see Victor changing his mind."
The Latics are obviously keen to keep hold of Moses, but should the £10 million asking price be reached, the club will not stand in his way.
