Sancho, 25, is one of four Man United players that missed out on the club’s pre-season tour of the USA after been told to find a new club this summer.
Several reports have suggested that the winger is on the verge on joining Juventus, but following the signing of Francisco Conceicao, that could now be in jeopardy.
According to Gianluca Di Marzio, the club have now suspended talks over a move for Sancho and will have to sell at least one winger to make a deal happen.
Nico Gonzalez and Timothy Weah are both expected to leave this summer, with the latter understood to be in talks over a move to Marseille.
