Rashford, 27, admitted in a bombshell interview last month that he is ready to leave his boyhood club, and he has not played under Ruben Amorim since.
The England international has made just one matchday squad in the past month, and is now being linked with a potential move abroad.
While AC Milan and Barcelona have both been linked with a move for the Red Devils winger, it appears that German side Borussia Dortmund are stepping up their pursuit.
According to German outlet Bild, Nuri Sahin’s side are desperate to bring in reinforcements in January after a dismal first half to their campaign.
They currently sit 10th in the Bundesliga and, after selling Donyell Malen to Aston Villa, are now keen on bringing Rashford in during the window.
The outlet claim that there has been considerable discussions at the German club over a potential loan move for the forward.
