Highly-regarded coach Julian Nagelsmann said Thursday that he will quit Hoffenheim to take charge at Bundesliga rivals Leipzig -- but only after the end of next season.

Nagelsmann, just 30 years old, became coach at Hoffenheim in 2016 and guided them to third place in the table last season.

On Thursday, he penned a deal with Leipzig which will run until 2023.

"It was important for me to have an early clear attitude," said Nagelsmann.

"In this industry, we always demand honesty, which is what we have proved and I expect others to respect that, too."

Sixth in the Bundesliga last season, Leipzig are without a coach for the 2018/2019 campaign after the departure of Ralph Hasenhüttl.
