Lucien Favre got the best of Jadon Sancho, gave Marc-André ter Stegen his top flight debut and tamed Mario Balotelli.
The Swiss coach has already turned German clubs into European contenders and now could have the chance to do the same at Newcastle.
Favre was named as one of the favorites to replace Steve Bruce at Tyneside after the Magpies’ £ 305million takeover was finalized.
The Saudi-backed consortium, backed by Amanda Staveley, has the ambition to make the club one of Europe’s elites.
Favre has become Newcastle’s favorite for the job given his track record of transforming underperforming teams in the Bundesliga.
The 63-year-old guided Hertha Berlin from 12th to fourth place in the two seasons following taking office, while Borussia Mönchengladbach were at the bottom of the league when he took office in 2011.
Under Favre, Die Fohlen avoided relegation, witnessed the emergence of Marco Reus and qualified for the early stages of the Champions League the following campaign.
In his two full seasons at Dortmund he secured second place behind Bayern Munich, but there has been a lot of talk about the end of his time at the club.
Favre ditched Sancho for returning late from his England service before a drop in form and a criticism of his tactics brought him to the brink of collapse.
Just weeks before his sacking, BVB CEO Hans-Joachim Watzke hinted at his exit saying: “A happy fart never comes from a miserable ass.”
However, there is no denying that Favre achieved instant success wherever he went – a key request for Newcastle’s new owners.
But the former midfielder may have some personal requirements to form his own squad, having even vetoed the planned signing of Stephan Lichtsteiner from Dortmund before he officially takes office.
Favre then assembled an incredibly exciting squad of young players in Sancho, Erling Haaland, Giovanni Reyna, Jude Bellingham and Reinier.
With Newcastle’s new unlimited budget, hottest names Aaron Ramsey and Philippe Coutinho have been linked as the first new signings.
But any player who arrives at St James Park under Favre “must be prepared to suffer in training”, as himself once said.
A host of current Newcastle stars will also be eliminated under a new manager, but Allan Saint-Maximin is definitely one of the fans who want to stay.
Unfortunately for Toon’s loyalists, the French striker does not seem to have the best relationship with managerial target Favre.
The pair worked together in Nice, Favre was reportedly enraged by Saint-Maximin’s behavior during the winger’s first session at the club.
Athletic claim that the Swiss coach broke into the president’s office after training to demand that he be sold due to his lack of “tactical intelligence”.
Favre was also reportedly frustrated with Saint-Maximin’s desire to drool over the development of his final product, according to the report.
The break with the No.10 Newcastle remains a stain on Favre’s reputation as an excellent man-manager with Reus one of his public supporters.
The German said: “I have had quite a few club coaches. And among them he is probably the best I have ever had.
Another, Mario Balotelli, who is known to fall out with his coaches, has benefited from a career resumption under Favre in France.
The former Manchester City and Liverpool forward told BeIN Sports: “He’s improved me a lot, especially tactically. Before, I worked on instinct.
“I discovered a great coach. He is very good tactically, but also in the way he manages the dressing room.
Favre, who was injured twice while passionately celebrating Dortmund’s goals, looks like a good choice for Newcastle fans who finally have something to celebrate.
