Manchester United boss Ralf Rangnick says assistant manager Chris Armas has had a positive impact.

Armas was brought from the US to help Rangnick.

He said, “Very helpful. We haven't worked together before that, the same is true with Ewan Sharp but with Chris Armas, we knew each other from our mutual time with Red Bull when he was head coach and assistant coach with New York Red Bulls.

"He's very helpful, not only very loyal but also very helpful and it's very helpful he's a native speaker. He knows how to communicate with players and he also had a high level of respect now from the players, they know that he's a good guy and also a good expert in different areas.

"I'm very happy to have him on board."
