Rangnick’s work permit has been granted, meaning he can now resume as United's interim manager.
Ex-Manchester United left-back Mikael Silvestre believes Ralf Rangnick has what it takes to turn United into Premier League champions.
The Red Devils sealed the services of Rangnick as interim manager on a six-month, and will move into the boardroom as part of a consultancy role for two years.
Rangnick will be in the stands at Old Trafford to see his new players today Arsenal on Thursday night, and will be keen to get a response to revive their top-four bid.
However, Silvestre, reckons the German should have been handed the United job on a permanent basis.
'Rangnick is good news. We know what he wants from his players, he has a plan and knows how to execute it. It's a good appointment, I'm pleased with it,' Silvestre, who played for United between 1999 and 2008, told the Sun.
'It is smart because it gives both sides time to see if there is a match - from the club's management and Ralf's perspective.
'There is a mid-term plan and it could be the one that takes United to being title contenders. Not this season but his mission is to finish in the Champions League which is hard enough.'
The ex-France defender continued: 'You have to be sensitive and consider the gap in quality and performances.
'There is enough quality in the squad to finish in the top four - that is where they should finish.'
United head into the game against Mikel Arteta’s Gunners in 10th position in the Premier League, six points off fourth-placed West Ham.
