“I only want to be a coach,” he told Sport 1. Those seven words are a good window into why the 47-year-old’s spells tend to sour: he is exceptional on the training pitches and in the technical area, but struggles to find common ground with boards, staff, some players – as the spat with Kylian Mbappe showed – and the media.
It feeds into the testimony of many who have worked with him during his last three jobs at Mainz, Borussia Dortmund and PSG, where there is no shortage of appreciation for his football brain, but also a warning that he is wired to fall out with plenty both privately and publicly.
At Dortmund there was a breakdown in the relationship between Tuchel and their former chief scout Sven Mislintat over the recruitment of Oliver Torres. The deal had been negotiated but Tuchel changed his mind during the closing stages of the transfer and it was never completed.
To the club, it felt like a betrayal of their processes and faith in their transfer diligence.
BVB chief executive Hans-Joachim Watzke and Tuchel also clashed over the handling of the situation after the team bus was attacked by roadside bombs in April 2017.
The manager understandably did not want his squad to line up against Monaco only a day after they were so shaken up by the incident, but Dortmund’s hierarchy insisted he never communicated that stance.
The divisions were growing deeper and in an article with Süddeutsche Zeitung, a BVB source was quoted as saying: “We were warned by Mainz that it would likely become difficult. We didn’t listen. For a year-and-a-half everything was great. Then everything was just as Mainz said it would be.”
The club on the Rhine River, which gave Jurgen Klopp his first managerial opportunity, have never been more successful than under Tuchel. And yet one staffer described him as “the biggest headache every day.”
Watzke admitted that “with Thomas Tuchel at the helm, Dortmund enjoyed two successful years in which our sporting objectives were achieved,” but added the kicker that “what matters are fundamental values such as trust and respect.”
In Paris, there were continual clashes. Leonardo, the sporting director, never warmed to Tuchel and his predecessor, Antero Henrique, had also grown tired of dealing with him.
The impressive Borussia Monchengladbach assistant coach, Rene Maric, also owes his career path to him.
And back in 2016, Klopp had timed his Dortmund departure announcement primarily to give the club a chance of securing Tuchel’s services because he felt he was the best emerging manager in the game.
His credentials, his influence and his CV cannot be questioned. However, a few of Tuchel’s former colleagues believe he was most comfortable in youth football, where development and tactical progression were the ultimate success.
There was no media security, transfer circus or hierarchies: just a pure focus on the play itself.
It is undoubtable that Tuchel will eventually manage in the Premier League: he has long wanted to, and clubs will be drawn to his work. Chelsea are an obvious match given their squad make-up of talents recruited predominantly from the Bundesliga along with academy graduates that have high ceilings.
Frank Lampard, though he insists he is confident, is under pressure after four defeats in six matches and failing to impose themselves on any side in the top half of the table.
Chelsea were interested in luring Tuchel before, as were Manchester United, while Mikel Arteta’s position is not concrete at Arsenal.
While he prefers a break between managerial roles, an opportunity in England’s top-flight might present itself sooner than he anticipates given the weird state of the season.
In order to succeed in this division, however, Tuchel will have to learn to navigate the elements of the job beyond being out on the training pitches and in the dugout a lot better than he previously has.
