63-year-old Uruguayan Jorge Fossati will head the national team, according to a tweet shared late on Saturday by the Qatar Football Association.
He replaces Jose Daniel Carreno, who was sacked on Friday after Qatar lost to Iran and Uzbekistan leaving them bottom of a six-team group in the final round of the Asian qualifiers for the 2018 World Cup.
Fossati, who has coached in Saudi Arabia and who managed Qatar between 2007 and 2008, is currently manager of Qatari club Al Rayyan.
It is unclear if he will retain his job at the club.
