As a replacement for veteran Colombian striker Radamel Falcao, who is keen on joining Turkish side Galatasaray, the former Toulouse forward has signed a five-year contract with Les Monégasques after spending three seasons in LaLiga.
"I am very happy to be involved with AS Monaco," Ben Yedder told his new club's official website. "I felt a strong desire on the part of the club to have me come.
"I chose Monaco because I believe in this project and I am determined to do everything possible to go after our common goals. I come with the intention to prove, as always, my qualities and with the desire to reach a new level.
"I want to thank the club for the trust it gives me. It's a beautiful day and the beginning of a new story that I cannot wait to start."
Sevilla recruited Ben Yedder from Toulouse in 2016 for a reported fee of €9 million, signing a five-year contract at the Ramon Sanchez-Pizjuan Stadium.
Confirming the deal, Oleg Petrov, president for Monaco disclosed the need for the signing of the 29-year-old goal poacher.
“Wissam is a player of great talent, a complete striker, who proved in Toulouse and Seville, but also in international competitions, all his sense of purpose. He is also a player with an exemplary mentality.
"His arrival is an important moment for Monaco. It demonstrates our desire to build an ambitious team to achieve the goals of the club."
