Adnan Januzaj has linked up with David Moyes once again at Sunderland

Sunderland have announced the signing of Manchester United forward Adnan Januzaj on a season-long loan.

The move reunites the 21-year-old with manager David Moyes who gave him his debut for the Old Trafford side in the summer of 2013.

Januzaj earned rave reviews for his performances over the next few months and was rewarded with a five-year contract which runs out in the summer of 2018.

However, he failed to hold down a regular first-team spot and was loaned to Bundesliga side Borussia Dortmund for the first half of last season.

Speaking at his press conference ahead of Saturday's trip to Manchester City, Moyes, who raided United for fellow 21-year-olds Paddy McNair and David Love just 24 hours earlier, said: "Adnan will give us a different variation.

"I thought he was one of the finest young talents I have ever seen, and he was up there with Wayne Rooney at the age of 18.

"I have to get him back to the level he played at two years ago. He will get every opportunity to do the business and I'm hoping the Sunderland fans will see the real Adnan Januzaj."

And United boss Jose Mourinho says Januzaj, who has been capped six times at senior level by Belgium, has a future at Old Trafford, insisting: 'we want him back'.

"He fits in my plans and that is why he's on loan, and on loan at a Premier League club," said the Portuguese. "If he doesn't we don't care about where he is going, which club, which competition, which manager, and maybe we send him to Borussia Dortmund where he didn't play one match.

"We care about him and we think he is a talented player. But to be in a squad with Memphis, Martial, Mkhitaryan, Young, Mata would mean not many matches.

"So we cannot be selfish and have to think about the players; in this case Adnan. We see him every week in this country. We can compare performances. He is in the right place with a manager that likes him a lot. We want it to go well because we want him back."

Sunderland have also signed Senegalese centre-back Papy Djilobodji from Chelsea and all four new recruits are in line to make their debuts at the Etihad this weekend.
