"In the six months I had him, there wasn't a single discipline problem. On the contrary. He is a calm and pleasant guy," Rangnick said in an interview with Sky Sport Germany.
"He had his best time in Dortmund and, when he was healthy, always played for me.However, he wasn't as carefree as in Dortmund.But that was also due to the overall situation.When he was fit, he was set and did well under me.He no longer had a chance in Manchester [this season].He now has to get back into a rhythm and really into shape in Dortmund.From his point of view, the change makes perfect sense."
