The Ligue 1 champions have already signed Youri Tielemans, Soualiho Meïté, Jordi Mboula, Diego Benaglio, Jordy Gaspar and Terence Kongolo as they bid to defend their league crown.
They started off their campaign with a 3-2 win over Toulouse this past weekend, and now have another option to consider.
The 25-year-old international footballer joins the club on a four-year contract from Lyon, where he played since joining the club’s youth academy, scoring 11 goals in 86 Ligue 1 appearances.
Speaking to the club’s official website, Ghezzal said: “I have the ambition to play at the highest national and international level, and the Monaco sporting project, which won the title and has reached the semi-finals of the Champions League, is fantastic.
“After several seasons in Lyon, I needed a new challenge. Everything is present here to make a great season. I cannot wait to meet my teammates and start training.”
Tiemoue Bakayoko, Bernardo Silva and Benjamin Mendy have all already left Monaco, while Kylian Mbappe and Thomas Lemar have been linked with moves away.
On the addition of Ghezzal, Monaco vice-president Vadim Vasilyev said: “We welcome Rachid Ghezzal, whom we have been following for some time. “He is a talented young player who knows our championship well but also has a solid experience in the Champions League. We believe a lot in Rachid.”
