The American coach worked under Rangnick at the New York Red Bulls and RB Leipzig and considers the German as his mentor in the coaching world.
Rangnick took charge of Manchester United in December and while results have been solid, some of the performances have not been up to the mark in the first few months of his time at Old Trafford.
However, Marsch stressed that some of the criticism of the German has been harsh as Manchester United’s problems are much more deep-rooted and long than what has happened in the last six weeks.
But the American stressed that there are signs that the team are gradually getting used to Rangnick’s ideas and at some point, his vision will come together on the pitch for the team.
“What’s been said so far is harsh”, Marsch told The Athletic.
“Manchester United have been in this phase where the club is having a hard time getting on track — for years, not just the last six weeks.
“It’s natural to hope for an immediate response and in some ways, they’ve had a response.
“Hopefully in the next few games it will click, there will be a moment where it all comes together.
“You will start to see his idea coming together.
“I have seen signs of it.
“For example, the second goal in the draw with Aston Villa [last weekend] came from a really good press to win the ball and they played on the transition.
“They’re looking more organised against the ball — we say that phrase rather than just ‘defensively’. They are getting better and better at counter-pressing.
“So yes, I think it’s coming together.”
Rangnick has lost just once since taking charge of the Manchester United side and has managed to keep them in the hunt for a top-four spot this season.
