United are looking to bolster their midfield ranks and Juventus man Emre Can has been among the names linked with an Old Trafford move.
According to Italian outlet Tuttosport, the Serie A giants will let the German leave the club in January as the Red Devils links appear to intensify.
However, the likes of Bayern Munich and Paris Saint-Germain are said to be ready to rival United for the midfielder's signature when the transfer window reopens.
United are struggling for midfield options this season after failing to replace Marouane Fellaini and Ander Herrera in the summer.
The Red Devils are interested in the former Liverpool man Can who has fallen down the pecking order in Turin following the arrival of Maurizio Sarri.
The 25-year-old is contracted to Juventus until 2022 but the Italian side are reportedly ready to let him leave on a cut-price deal in January.
