Former Manchester United star David Beckham has told Sky Sports News that Jose Mourinho can deliver titles and ensure the club is "feared again."
United have won only one major trophy -- the 2016 FA Cup -- since Sir Alex Ferguson concluded his reign with the 2012-13 Premier League title.
However, Beckham, who won six titles under Ferguson before leaving for Real Madrid in 2003, is confident Mourinho will prove a more successful appointment than predecessors David Moyes and Louis van Gaal.
"I fully expect it to work," he said. "With Jose leaving Chelsea and now coming back into the Premier League with United, for me it is a great move.
"I had huge respect for Van Gaal, but it did not work out the way people expected it to. But I think at the end of the day, now it is a new start for United.
"We have had a couple over the last three or four years, which is not the Manchester United style, who are used to a manager like Sir Alex Ferguson being in there for so many years, but we've had quite a lot of change over the last few years.
"So now with Jose in there, he knows what he wants and how to get it, he knows how to win titles.
"I think that is what Man United definitely need to get back to and they need to get back to being feared again.
"Because we were always a club -- and are still a club -- that when teams come to Old Trafford, they know they are going to be up against it and they know they are probably going to lose. So that is what we need to get back to."
Mourinho has moved quickly to reinforce his squad, with Zlatan Ibrahimovic, Henrikh Mkhitaryan and Eric Bailly already signed up and Paul Pogba tipped to follow, and Beckham believes they can be contenders this season.
Asked who he expected to win the title, he replied: "I am going to have to say United. I will always be on that side of the fence."
