One of the most promising managers in world football dubbed 'mini Mourinho', aged 32, has been hailed as a better tactician than Manchester City boss Pep Guardiola.
RB Leipzig head coach Julian Nagelsmann has once again enhanced his reputation in his debut season with the ambitious club as they sit in third place in the Bundesliga.
Nagelsmann transformed Hoffenheim from relegation candidates to a side challenging for Europe after assuming his role as manager at the age of 28. And the man dubbed the mini Jose Mourinho was subsequently linked with Manchester United and Arsenal.
However, he opted to join Leipzig, where he's steered them to 23 wins in 41 games with an exciting brand of attacking football that's produced 99 goals across all competitions.
And Hoffenheim's former head scout Lutz Pfannenstiel, who worked alongside the youngest manager across Europe's top-five leagues at his first job believes his tactical knowledge is unparalleled.
"Julian is a driven man, a perfectionist. He can't lose - and it doesn't matter whether it's a competitive game or a casual duel in table tennis, a round of Mikado or a duel with me on penalties," he told DAZN.
"Very good is not good enough for him; that became clear at a young age. So, it is no surprise that he is probably the most exciting coaching talent in Europe today."
During his stint at TSG, his meteoric rise started with the U-17 squad before he quickly moved on the U-19s, the first-team assistant and eventually the head coach role for three years.
"He knows what it's like being in a relegation battle and the Champions League. Therefore I would say Julian is probably the most exciting coach at the moment.
"Julian is even better than Pep Guardiola when it comes to reading the opponents' style of play and adjusting the tactics accordingly during a game.
"Pep is someone who analyses a lot and then makes a decision. With Julian, the analysis runs parallel to the observation. We're talking about a very small window of time, but it can be crucial.
"Incidentally, this is not a talent, but a gift. I've met a lot of coaches, but Julian has this quality exclusively. It is unique."
