Arsenal midfielder Reiss Nelson says he's appreciated working with Hoffenheim coach Julian Nagelsmann.
Nelson moved to TSG on-loan this season.
He told The Sun: “I've got a lot of time and respect for Arsène, and I think he developed me into a good young man as well, and I'm very thankful for that.
“But coming to Hoffenheim, Julian is a bit different - he has a different style, he likes to look at the opposition and change the team. He's very tactical.
“It was difficult at first because not very much was explained in English. I had to learn very quickly and adapt to the German language.
"On my debut, I came on in the 70th minute. The ball went over the top and I just heard everyone shouting 'weiter, weiter, weiter'. I didn't know what they were talking about! I realised it meant run, run, press, press. That's the intensity you want to play at. It can only make me better.
"After a few training sessions and being on my toes, I got it."
