Manchester - Belgian winger Adnan Januzaj has joined Sunderland on a season-long loan from Manchester United, his new club announced on Friday.
The move will reunite Januzaj, 21, with Sunderland manager David Moyes, who gave him his United debut in August 2013.
Januzaj made a strong impression in the 2013-14 season, but failed to hold down a first-team place at United and spent the first half of last season on loan at Borussia Dortmund.
"Adnan will give us a different variation," Moyes told a press conference. "I have to get him back to the level he played at two years ago.
"He will get every opportunity to do the business. I'm hoping the Sunderland fans will see the real Adnan Januzaj."
Sunderland have not revealed if the deal contains an option to buy.
Januzaj is the third United player to have joined Sunderland this week, after fellow 21-year-olds Paddy McNair and Donald Love signed on permanent deals on Thursday.
Sunderland have also signed Senegalese centre-back Papy Djilobodji.
Sunderland open their Premier League campaign at Manchester City on Saturday, when all four new signings could make their debuts.
