The 30-year-old has been out of action since suffering an injury in training while Jose Mourinho was still in charge.
Ole Gunnar Solskjaer has since been appointed as the club’s interim boss until the end of the season as he looks to try and steer the Red Devils back into the top four before the campaign is over.
Sanchez has recently returned to England to step up his training after spending some time out of the country to work on his rehabilitation.
And the former Arsenal star looked to be in a determined mood as he worked on his fitness levels at Carrington this week, taking part in a number of drills on his own.
Sanchez shared a series of videos on his personal Instagram story as he looks to try and get himself into shape as soon as possible.
It remains to be seen whether Sanchez could be set for his first appearance under Solskjaer when the Red Devils host Bournemouth in the Premier League at Old Trafford this weekend.
