Former Arsenal striker Thierry Henry has been appointed as head coach of Monaco until June 2021.
The 41-year-old Frenchman, who had been Belgium's assistant manager, began his professional career at the Principality club and helped them win Ligue 1 in 1997.
However, Monaco are struggling at present, sitting third from bottom in Ligue 1, prompting the dismissal of former manager Leonardo Jardim on Thursday.
The former France forward, who won the World Cup with Les Bleus in 1998, was linked with the Aston Villa job following Steve Bruce's sacking last week, but Dean Smith was eventually appointed.
"I am very happy to come back to Monaco and extremely determined to meet the challenges ahead," Henry told reporters.
"I cannot wait to meet the players to start working together."
