“It's a league I know well, in which I had some very nice moments. To be in Quebec, in Montreal, which has an enormous multicultural heritage, it's extraordinary. I've always kept an eye on the club and now I'm here."
Henry will be formally presented at a press conference on Monday and will begin his new management stint in January.
“We are extremely happy to announce the nomination of this legend of the game," added Montreal Impact president and CEO Kevin Gilmore.
“Henry will bring a new energy to our club. He shares our vision to elevate this club and will help us achieve our goals on and off the field. He is a competitor and a leader who has proven himself at the highest level throughout his career.
"He now brings these qualities with him to Montreal, a place he wants to be."
