Thierry Henry has been appointed as new head coach of Ligue 1 club Monaco, replacing Leonardo Jardim.
Sources told ESPN FC on Friday that 41-year-old Henry would sign a three-year contract, and he takes charge of the club at which he began his professional career until 2021.
The former Arsenal and Barcelona forward will officially begin work on Monday, the club said in a statement.
Henry, who joined Monaco as a 13-year-old in 1991 and won the Ligue 1 title at the Stade Louis II in 1997, told the club's official website: "In the first place, I thank AS Monaco for giving me the opportunity to coach the team of this club, which is so special to me.
"I am very happy to come back to AS Monaco and extremely determined to meet the challenges ahead. I cannot wait to meet the players to start working together."
The transition to manager could be difficult for Henry
Former MLS managers Steve Nicol and Paul Mariner call upon personal experiences to offer Thierry Henry some coaching advice.
Monaco vice-president Vadim Vasilyev added: "Thierry is both aware of the task ahead and eager to start his new job. He can count on our trust and all our support to bring a new dynamic to the team and carry out the mission."
Henry had been working as an assistant to Roberto Martinez with Belgium and was on the bench for Friday's 2-1 UEFA Nations League victory over Switzerland.
He had previously been linked with Aston Villa, who instead named former Brentford coach Dean Smith as boss on Thursday.
"It is with great pride that I am delighted to announce that I have accepted the position to become the manager of AS Monaco FC," Henry wrote on Twitter.
"I was fortunate to receive some very attractive offers over the last few months, but Monaco will always be close to my heart.
"Having started my football career with this great club, it seems like fate that I will now begin my managerial career here too.
"I'm incredibly excited to be given this opportunity but now the hard work must begin. Can't wait."
Henry, who made his senior Monaco debut under then manager Arsene Wenger in the 1994-95 season, was voted French Young Player of the Year a season later.
Monaco, Ligue 1 champions two seasons ago, are in the relegation zone after winning just one of their first nine matches this term.
Sources told ESPN FC on Tuesday that Jardim was to be sacked and replaced by Henry and, after the Portuguese coach's dismissal was confirmed on Thursday, the way was clear for Henry to be hired.
Monaco's next match is at Strasbourg on Saturday Oct. 20.
