United could make a move for the Wigan ace in the January transfer window, but it is more likely that it will happen at the end of the season.
A close pal of Palacios told The Sun: “You know the rapport between Steve Bruce and Alex Ferguson. They’re very close.
“United have been following Wilson closely for some time. Steve benefited from his rapport with Sir Alex and was able to keep Wilson for six months or a year more.
“Nothing is signed but there’s a moral agreement. Wigan have set the bar high, £18m. It’s possible it could be done in January.”
Palacios joined the Latics for just £1million from Birmingham last January.
