The Italian enjoyed a strong end to the 2016/17 season but has since frustrated supporters with a series of turgid, technically deficient displays at full-back.
He has only made two Premier League starts this season and his only appearance this calendar year came against Yeovil Town in the FA Cup.
And Schira recently tweeted that Darmian, who had returned to Italy for a shopping day with his partner, was in pole position to join Juventus and had been greeted by supporters inviting him back to Serie A for next season.
Giornata di shopping milanese per Matteo #Darmian. In estate si profila l'addio al #ManchesterUnited e il ritorno in Italia, con la #Juventus in pole. Ai tifosi che oggi l'hanno incrociato, invitandolo in bianconero il terzino ha risposto con un sorriso #calciomercato pic.twitter.com/g75xFujXOc

“Milan Shopping day for Matteo #Darmian. In summer the farewell and return to Italy is looming #ManchesterUnited, with the #Juventus [in] pole [position].
“To the fans who today have come across him, inviting him in black [and white] and the defender responded with a smile.”
A move back to his homeland – a footballing culture which aligns much better with his style of player – seems like the only sensible decision for a player who has, along with the injured Daley Blind, dramatically fallen down the pecking order this season.
They have both gone from decent utility players to looking like painful relics from a failed Louis van Gaal era this season, incongruous and directionless, and you imagine they will be the first to depart Old Trafford as Mourinho looks to revitalise his options at full-back during the window.
