Mkhitaryan's future with Manchester United is uncertain with the Armenia international currently out of favor at Old Trafford.
The former Borussia Dortmund star started the season in fine fettle, racking up five assists in two games against West Ham and Swansea.
But, in the time since, Mkhitaryan has toiled with the Manchester United player last featuring against Chelsea at the beginning of last month.
TransferMarketWeb say that after not lining him up since losing to Chelsea, last November 5, Mourinho went for an emergency meeting with Mkhitaryan, 28.
"If the player forces Manchester United to put him for sale (or loan, at least) next January, both Borussia Dortmund and Inter Milan might act on trying to sign him," the publication says.
