The 23-year-old moved to Old Trafford in a £73m transfer from German club Dortmund in July 2021.
After a falling out with manager Erik ten Hag, he hasn’t played for United since August 26. Since September, he has been practicing apart from the first team.
There is no buyout option in the loan agreement.
“When I came into the dressing room today, it felt like ‘coming home’,” Sancho stated.
“I’ve always had a close relationship with the fans here, I know the club inside and out, and I’ve never lost touch with the management.”
“I can’t wait to see my team-mates again, go out on the pitch, play football with a smile on my face, prepare goals, score goals, and help qualify for the Champions League.”
