Julian Nagelsmann will not take up the role as Paris Saint-Germain head coach after talks between the two parties broke down, according to reports.
The German has been out of a job since being sacked by Bayern Munich in March, with former Chelsea boss Thomas Tuchel immediately replacing him, and is apparently no longer being considered for a first managerial role in France.
Nagelsmann was favourite to take over at the Parc des Princes after Christophe Galtier was sacked at the start of June following just one season at the club.
Intense negotiations had taken place over several weeks between Nagelsmann and PSG decision-makers, however discussions failed to find a suitable agreement, as first reported by L'Equipe.
The 35-year-old will now be left to seek out other opportunities unless PSG and himself agree to U-turn on their apparently concrete decision.
It was previously reported that positive talks had taken place and the Ligue 1 champions were edging close to an announcement as Nagelsmann looked set to take up his fourth permanent role in management.
It even appeared that the Bundesliga-taught coach had already began to identify potential members of his backroom staff with Thierry Henry earmarked as his number two.
The failed appointment at the French giants marks a third missed managerial opportunity after Nagelsmann was previously linked with Premier League vacancies.
There was initial interest from Chelsea who were considering the German before deciding to hire Mauricio Pochettino, while Tottenham were another reported destination.
Meanwhile, PSG are reportedly considering other high-profile names and could be in a position to name a new head coach as early as next week.
Bologna manager Thiago Motta has reportedly been mentioned amongst the favourite candidates, having previously embarked on his first stint in management with PSG's Under 19s team.
Former Spain and Barcelona coach Luis Enrique is also another possibility as the French side continue their search for a fourth manager in five years.
