When Thomas Tuchel arrived at Chelsea in January to take over from Frank Lampard, the German was well aware of the club's strict policy with managers.
The former Paris Saint-Germain boss understood the pressures of accepting the role at Stamford Bridge but was insistent that he wasn't scared to face the demands outlined by the board.
Tuchel revelled in the swarming media attention, relishing the chance to star as the Premier League's newest golden boy before validating his plaudits by leading Chelsea to Champions League glory.
However, the Blues boss' greatest quality in his opening months in west London was his personable character and man-management techniques that had the Chelsea squad and media singing from the same hymn sheet.
Tuchel had tranquillised his new squad, handing fresh starts to the likes of Marcos Alonso, Antonio Rudiger and Andreas Christensen who had all suffered difficult tenures under Lampard.
But, despite heading into the international break top of the league, Timo Werner has seemingly ignited a cause for concern that the former Paris Saint Germain boss must solve to ensure that he doesn't fall into the same trap Felipe Scolari did in 2009.
Scolari was appointed as Chelsea boss in July 2008, just six months or so after the arrival of Nicolas Anelka from Bolton for £16 million in January, before his inability to tend to the Frenchman's and Didier Drogba's needs saw him dismissed from his position.
Drogba began the 2008/09 season injured which opened the door for Anelka to enjoy a run of games leading the line and Premier League goal-scoring charts, but when the Ivorian returned Scolari was unable to weld the two striker's together.
"Our medical department thought that we should let Drogba go and recover [from surgery] in Cannes, in the middle of summer,” Scolari told Yellow and Green Football.
The former Chelsea boss continued, as his recollection poses as a warning to similar difficulties Tuchel is beginning to face with Werner and Lukaku.
"When he came back, I tried to adapt so that Drogba and Anelka could play together," he said. "Anelka was the top scorer in the league. We had a meeting and Anelka said: ‘I only play in one position.’
“They were both great, but someone had to do something different, to get back to help when we lost the ball."
Scolari was eventually sacked in February that season and Carlo Ancelotti was then appointed at Chelsea to strike a tune from both Drogba and Anelka, despite both being branded as out and out number nines by trade.
The Italian boss did just that and helped the pair develop grow a greater understanding of one another that yielded a Premier League, FA Cup and Community Shield.
Speaking in 2009 after a 2-0 win over Fulham which saw the pair combine for either goal, Drogba vowed his eventual understanding with Anelka to the time Ancelotti gave them.
"We are intelligent people and we know how to play together. We just needed time," Drogba said.
While Anelka agreed, also speaking following the clash at Craven Cottage: "When he has got the ball he tries to look for me and I try to look for him," he said. "Of course, game after game when we play on the pitch together the understanding is better."
He then added how Ancelotti's man management ensured that he no longer wanted to leave Chelsea, which Tuchel should learn from following Werner's most recent interview hinting at a move away from Stamford Bridge.
Anelka said: "Everything is going well and I don't need to move anymore."
Similar to the former number 39 in his early days under Scolari, Werner described his last few weeks at Chelsea as 'difficult' following the recent arrival of Lukaku, who has seemingly stolen his limelight as the club's designated number nine.
Speaking to the German outlet, Express 24, Werner said: "The last few weeks have been difficult at Chelsea. After many years, I was suddenly a little behind and had to fight my way again.
"I would like to enjoy more minutes, so I give my best in training. I can’t be satisfied if I don’t play. Of course, I want to be a regular in a big team. I’m not saying that if I don’t start 10 or 15 games before Christmas, I really want to leave.
"Things happen quickly in football. I have to look at the bigger picture to make my decision."
Tuchel must notice the striking similarities between Werner's emerging rift at the Blues and Anelka's under Scolari, so the German boss should learn from Ancelotti's ability to accommodate both should he eye the fate of the Italian.
So, whether Tuchel looks impose a greater emphasis on a two strikers or simply reintegrate Werner back into the front three, the Blues boss should look to ensure squad harmony is central to his plans otherwise he could be dealt a similar fate to Scolari.
