Manchester United legend David Beckham has insisted that the Red Devils will remain a force with David Moyes in charge.
Moyes took charge of the Red Devils at the start of July after Sir Alex Ferguson announced his retirement at the end of last season.
And, so far under Moyes, United have struggled this season - losing three of their opening six Premier League matches.
However, despite United's early season troubles, Beckham believes his old club will continue to succeed under Moyes, but the ex-England captain believes the Red Devils are currently going through a transitional period with their new manager.
Speaking to The Telegraph, Beckham said:"There was always going to be that moment when Sir Alex Ferguson retired.
"Who was going to take over? What was it going to be like when a new manager came in?
"Were they going to be the same force as they have been over the last 20 years?
"They will be because they are Manchester United.
"There’s a transitional period that will happen but David Moyes is a very good manager."
Beckham's old club travel to the Stadium of Light this evening to take on bottom of the league Sunderland and United will be desperate to get back to winning ways.
The Red Devils have suffered back-to-back league defeats so will know the importance of securing three points against the Black Cats.
