The Algerian worldwide star looks certain to sign for someone today, as the Algerian football federation released a statement declaring that Mahrez had been given permission to leave the national squad's training to sort out his transfer.
In a statement released on Twitter, the Algerian Football Association said: "Mahrez [is] allowed to go formalise his transfer to a new club".
Mahrez submitted a transfer request earlier this summer, but he has been unable to seal a move with Italian giants Roma failing with numerous bids.
French outlet SFR, as quoted by Metro, is reporting that the Portuguese coach is keen to bring the 26-year-old Algeria worldwide to Old Trafford but is yet to convince the Manchester United board to make the move.
Mahrez's destination remains unclear, but it seems likely that the former Premier League victor will leave the King Power Stadium before the transfer window shuts.
Sky Sports reports no bids have been made for Mahrez since Roma's £32m offer was rejected more than three weeks ago.
Liverpool have so far rejected three bids for the Brazil global, but Barca are expected to return with a fourth offer, reported to be worth around €160 million including variables, before the end of the week.
Tottenham, Arsenal and Chelsea were among the first clubs linked after those claims, and they have been repeatedly since.
