Julian Nagelsmann has been sacked by Bayern Munich, with Thomas Tuchel confirmed as his successor.
The Bundesliga champions are struggling domestically this season and lie second behind Borussia Dortmund.
Nagelsmann, who has not been at the training ground this week, is understood to have lost his job because the team has gone backwards in the league and the hierarchy have not seen enough player development.
Players and bosses at Bayern were also surprised to see that the 35-year-old was on a skiing holiday this week at such a pivotal time as they feel it sends the wrong signal, according to Sky in Germany's Florian Plettenberg.
Tuchel, 49, has been out of work since being sacked by Chelsea in September under the new ownership of Todd Boehly.
The 49-year-old, who has been living in Munich for some weeks, has previously managed Dortmund and Paris Saint-Germain. Bayern's players were already aware earlier in the week that Tuchel would be their new manager.
