Jason Sancho will wear the no 10 shirt on his return to Borussia Dortmund.
The 23-year-old has left Manchester United to join the Bundesliga side on loan.
Sancho was officially unveiled on Thursday afternoon.
The move back to Germany will help Sancho play football again, as he has been frozen out at United since August.
United signed Sancho from Dortmund in the summer of 2021 in a deal worth £73m.
However, he has not featured for the Red Devils, since he fell out with manager Erik ten Hag.
Sancho’s contract expires in 2026, with United holding the option to extend for a further year.
