The Armenian attacking midfield started this season on a fine form making five assist in three matches for United but has failed to replicate such form in recent weeks.
His poor performance has led Jose Mourinho to oust him from his team starting eleven in United last five games across all competition.
He is currently behind Anthony Martial, Jesse Lingard, Marcus Rashford and Juan Mata in the Red Devils squad.
Report has it that Dortmund are monitoring his situation and will make offer for his services when the winter transfer window reopens.
The Bundesliga club are going through tough time at the moment. They are winless in their last 10 league matches and are 10 points behind league leader Bayern Munich in the league table.
Dortmund boss Peter Bosz is looking forward to January transfer window to strengthen his team and has set sight on former player Mkhitaryan.
The 28-year old midfielder spent three year at Westfalenstadion before moving to Old Trafford in 2016 summer in a £30m deal while becoming the first Armenian to play in a Premier League club.
The Sun also claims that United are preparing to make a £31millin bid for Atalanta midfielder Bryan Cristante, who could be a permanent replacement for Mkhitaryan or Marouane Fellaini.
