Manchester City have announced the signing of left-back Benjamin Mendy for £49.2m on a five-year deal.
The 23-year-old France international flew to Los Angeles to undergo a medical and compete the deal on Sunday ahead of joining-up with City's pre-season tour of the United States.
Mendy had been City's first-choice target for a new left-back and joins fellow new full-backs Kyle Walker and Danilo through the door at the Etihad, as City take their summer spending past the £200m mark.
Mendy said: "I am very proud. This is what I wanted from the very beginning. As soon as the championship was over, I talked to my family and it was all clear in my head: I wanted to join Manchester City.
"I think I am the right person for the group. I am easily adaptable. There are some players with whom I exchanged a few emails, I knew them from some years ago.
"Regarding football, I can bring a lot of creativity in the game, I can offer different solutions, I like to take to play as full-back and provide assists for the strikers."
Director of football Txiki Begiristain said: "Benjamin has all the qualities we are looking for in a full-back. For such a young player, he has a wealth of top-level experience"
Mendy was an integral part of that Monaco side that won the Ligue 1 last season
Mendy has emerged as one of the best left-backs in Europe despite just a single season at Monaco following a £13m move from Marseille last summer, and was one of a number of Monaco players of interest to other clubs following their French Ligue 1 triumph.
City have already signed Bernardo Silva from Monaco and are also interested in their highly-coveted striker Kylian Mbappe.
