The Italian, who impressed during the latter stages of last season, has been closely linked with Juventus after Dani Alves departed earlier this month.
And according to Premium Sport (via M.E.N), Man United will not let the Italian leave on a loan basis.
You can understand why Mourinho, after watching Adnan Januzaj fail so miserably at Sunderland, would be averse to letting many more players leave on loan.
In fact, Andreas Pereira – now back from a spell at Granada – can rightly consider himself the only United player over the last five or so years to visibly improve during a loan move. Sam Johnstone is another, but won’t return to Old Trafford after attracting attention from various Championship clubs.
Mourinho will not want to see Darmian spend nine months away and lose the newly discovered defensive nous and discipline that saw him excel during the April and May period of last season. He will, in fact, do everything to keep him at Old Trafford ith both Marcos Rojo and Luke Shaw set to miss the start of the upcoming campaign.
