His side may have performed admirably for periods of his tenure, but if Borussia Dortmund want to usurp Bayern Munich as the Bundesliga's top side, they may have to ditch manager Lucien Favre.
The Swiss tactician's contract is up at the end of the season. In the likely event that Bayern win their ninth successive title and Dortmund allow Favre's deal to expire, the next coach they choose must get the best out of this immensely talented side if they are to dethrone the Bavarian heavyweights.
Favre has brought through some talented youngsters like Jadon Sancho, Giovani Reyna, 16-year-old Youssoufa Moukoko, and Erling Halaand, though he may not have enough time in charge to see each star hit their peak.
Here's a look at a few managers who could replace Favre and bring Bundesliga glory back to the Westfalenstadion.
5. Massimiliano Allegri
Without a club since leaving Juventus in 2019 following five successive Scudetto wins, it appears Allegri has been grateful for some time away from elite football.
But could Dortmund be the ideal location for his return? While his managerial style doesn't really suit their attacking football ethos, his trophy haul speaks for itself.
It could be time for the German club to pursue other avenues if they want to really challenge Bayern Munich for the title, and who fits that mould better than Allegri?
An outside shot. Certainly a wildcard and definitely unlikely.
4. Roberto De Zerbi
Dortmund could really benefit from striking while the iron's hot here.
Into his sixth year as a coach, De Zerbi has his Sassuolo side rubbing shoulders with Italy's heavyweights towards the top of Serie A, playing fabulous, expansive calcio.
It would be a big step for De Zebri and indeed for Dortmund, but just imagine what he could do with Dortmund's young guns at his disposal.
3. Jesse Marsch
Tactically speaking, Marsch could not be more different from Favre.
Unlike Favre, Marsch does not value possession as an attacking metric. While Dortmund like to dominate the ball and refrain from shooting until there is a clear-cut chance, RB Salzburg have a more high-risk approach to winning games.
A strict tactician, he values pressing the ball, cutting passing lanes and picking up second balls to get results.
No one could deny that we'd see a more free-flowing Dortmund once again if Marsch was on the touchline at the Signal Iduna.
2. Ralph Hasenhüttl
After dealing with some troubling times at Southampton after his move from RB Leipzig, Hasenhüttl has proven that given time he can build one of the most resilient sides in the Premier League, despite having little resources to do so.
Under his watch, the Saints have become a defensively sound, well-balanced and dynamic team that can upset any side on their day.
The Austrian must be on the radar of many of Europe's top clubs. While Dortmund would do well to secure Hasenhüttl, who looks very settled in England, they could no doubt offer him a project he would thrive with.
1. Marco Rose
It's no coincidence Rose is the third successive coach in this list to have worked with the Red Bull faction of European football. Their desire to develop young talent is shared by the Dortmund hierarchy and fans alike.
Following his arrival form Salzburg in 2019, Rose helped Borussia Monchengladbach qualify for the Champions League for the first time since 2017. They're well placed to qualify from their group, which contains Inter and Real Madrid, following some immensely impressive performances.
Rose's playing philosophy, while statically astute, is built around hunger, desire and emotion, all characteristics that align perfectly with Dortmund.
Not only has he proven his quality in the Bundesliga, but he has also made Monchengladbach one of the most exciting teams around.
