Marcello Lippi - who won the 2006 World Cup with Italy - has come out of retirement to become the new manager of China.
Lippi, 68, had two spells in charge of the Italian national team and won five Serie A titles and the Champions League with Juventus.
He retired from coaching after winning a third straight league title with Chinese side Guangzhou Evergrande in 2014.
China are ranked 84th in the world.
The Italian replaces Gao Hongbo, who resigned earlier this month after a 2-0 defeat in Uzbekistan dealt a further blow to China's slim hopes of qualifying for the 2018 World Cup in Russia.
They are bottom of Group A in Asia with one point from four games.
