Thomas Tuchel will arrive at Stamford Bridge with a reputation for rows and fall-outs.
Therefore, the former Borussia Dortmund and Paris Saint Germain boss should fit in just perfectly at Chelsea.
Tuchel, 47, does also have a decent CV, regarded as a good coach in Germany and has also delivered back-to-back titles in France.
His reputation extends to playing exciting, attacking and high energy football but managing big stars has consistently been an issue.
Furthermore, Tuchel had very public disagreements at PSG before eventually being sacked last month. It should make for an exciting ride at Chelsea.
That has made him a free agent, an attractive proposition for Chelsea as they made him their No1 target to replace Frank Lampard well before pulling the trigger.
But Tuchel also arrives with much to prove, a coach yet to reach the heights of Jurgen Klopp, his predecessor at Borussia Dortmund and unable to deliver the Holy Grail of European success at PSG.
It must be seen as a gamble by Chelsea as Tuchel arrives with a reputation for being a strong personality, abrasive and confrontational.
And normally, that comes with a record of success because you have to earn the right but it still feels as if Tuchel has yet to reach the levels of being an elite coach on the biggest stage.
Tuchel did lead PSG to the Champions League final and six domestic trophies, and yet ultimately it ended badly for him in France.
Tuchel struggled at times to manage the likes of Neymar and Kylian Mbappe, struggled to say the right thing and upset PSG’s hierarchy, first director of football Leonardo over signings and then the Qatari ownership.
He was quoted as saying he felt “more like a sports politician or sports minister than a coach” in his first season in France which caused upset.
Similarly, Tuchel was reported to have rows at Dortmund after a high profile fall out with former transfer chief Sven Mislintat.
The German media also wrote about spats with Pierre-Emerick Aubameyang and he was sacked in 2017 just three days after winning his first major trophy, the German Cup.
Tuchel has never hidden his desire to manage in England and is a disciple of the highly-regarded and respected German coach Ralf Rangnick.
The Bundesliga official website even reveals Tuchel’s fascinating rise from barman to Bundesliga coach within nine years.
Tuchel started as a defender, was released by Augsburg at 19 without making the first team, joined Stuttgarter Kickers and then SSV Ulm where he struck up a relationship with Rangnick.
He was forced to quit through injury at 24, studied Business Administration at university and took a part time job in a bar to help pay for his lessons and then hooked up again with Rangnick at Stuttgart where he took charge of the under-14s.
From there, Tuchel’s career took off, taking youth jobs, the reserve team at Augsburg before moving to Mainz where he got his big break as a manager in 2009 and led the club into the Europa League.
His reputation was established, he followed Klopp’s path and went to Dortmund but has yet to match the Liverpool manager’s success.
Chelsea have a strong German connection in the dressing room with Antonio Rudiger, Kai Havertz, Timo Werner and also ex-Dortmund forward Christian Pulisic in the set-up.
Tuchel also knows Thiago Silva from PSG. The reason Chelsea chose him is clear.
And Chelsea will also give him the platform to give him that opportunity to build on his reputation – both on and off the pitch.
