German sporting director Lutz Pfannenstiel believes Ralf Rangnick can be a success with Manchester United.
Pfannenstiel worked with Rangnick at Hoffenheim.
He told BBC Sport: "His football is very direct, lots of pressing, lots of counter-pressing, lots of high-intensity football - something which is always exciting to watch.
"If you look back at how Hoffenheim played, especially how RB Leipzig played, I think this is what you can expect - some really, really high push-up football where they are pressing and stressing the opponent, forcing the opponent to make mistakes.
"He is very clear, very direct and most importantly everything he does is with a clear goal. He is not a guy who jokes around all day. He wants things to get done - that's the way he will approach that. Ralf was always successful - and I believe he always will be successful because he is as intense as his football will be on the field. He expects a lot from the players, but he also expects a lot from himself.
"I think it really fits well to the players Manchester United have and to the style the fans love to see at Old Trafford. I think Ralf could be the next German who really puts his stamp and his legacy on a club's future."
The former goalkeeper added: "Ralf is a big expert, really one of the best coaches or managers Germany produced in the past 15-20 years, I would say.
"Everything he did so far was successful and he always was very clear that if he gets the opportunity to work for a big club in England, he wants to do that.
"So, looking at this interim head coach, I think he is the one who really can get everything stabilised to really get United back on track. I think he probably was the best man on the market."
