Despite its dazzling success, RB Leipzig is hated by many supporters across the Rhine, who mock its lack of history and its enormous financial resources. But as coach Gernot Rohr reminds us, the club has built an identity. 

It is an opponent still little known to the general public that is preparing to face PSG. Tuesday in Lisbon, the capital club will try to qualify for its first Champions League final against RB Leipzig. A club with dazzling progress, passed in a decade from the fifth German division to the last four of the Champions League, by the will of Red Bull and its billionaire boss, the Austrian Dietrich Mateschitz. But this success, combined with this economic power, did not increase the popularity of the club across the Rhine, quite the contrary.

The detractors of Leipzig indeed see it as a club assembled from scratch thanks to the millions of dollars of its sponsor. A team without history, a "plastic" club. And the marriage between this industrial city in the former East Germany and the Red Bull brand, symbol of triumphant capitalism, is unsettling. 

"The strength of Leipzig is its youth"

But the success of this team does not come only from the money. For German coach Gernot Rohr, interviewed by Europe 1, RB Leipzig has been able to create an identity. "The strength of Leipzig is its youth, its enthusiasm, its collective game", he explains, praising "its very high pressing, its fighting spirit in all areas", as well as its collective.

Symbol of this team, the ambitious coach Julian Nagelsmann, 33, has been able to unite around him and arouses the admiration of the greatest current coaches.
