Ligue 1 club Monaco have named Thierry Henry their new manager after Leonardo Jardim was sacked for poor performance.
The former Arsenal and France forward has signed a three-year deal with the Principality club. He is saddled with the task of improving the side's fortune after they recorded just one victory in nine league matches.
They are 18th with six points after nine games.
Henry will now leave his role as a member of the Belgium national team's staff.
The 41-year-old had been named a possible replacement for Aston Villa's Steve Bruce, who was sacked under circumstances similar to Jardim's.
The former striker will be joined by Joao Carlos Valado Tralhao, under-23 coach at Benfica, and Patrick Kwame Ampadu, coach at the Arsenal Academy.
Henry knows Monaco well having graduated from their youth system and making his professional debut in 1994.
He notably scored seven goals in the 1997-8 Champions League as the Monaco team of the time, then coached by Arsene Wenger, reached the semi-finals, where they lost to Juventus.
"First of all, I thank AS Monaco for giving me the opportunity to coach the team of this club which is so special to me," Henry said.
"I am very happy to come back to AS Monaco and extremely determined to meet the challenges ahead. I can not wait to meet the players to start working together."
After spending five seasons as a player with Monaco, Henry went on to play for Juventus, Arsenal, Barcelona and the New York Red Bulls.
Monaco chief executive officer Vadim Vasilyev, said Henry could "count on our trust and all our support to bring a new dynamic to the team and carry out the mission".
"His knowledge of football, his passion for the game, his high standards and his commitment to our colours make his nomination a reality.
"Thierry is both aware of the task ahead and eager to start his new job."
