Batshuayi becomes first Conte signing as Mendy joins Foxes
Chelsea have signed Belgium striker Michy Batshuayi from Marseille.
The 22-year-old moves for a reported £33million fee and has signed a five-year contract.
Batshuayi becomes incoming head coach Antonio Conte's first signing.
Batshuayi joins compatriots Eden Hazard and Thibaut Courtois at Chelsea.
In swapping Stade Velodrome for Stamford Bridge, he makes the same move Didier Drogba did 12 years ago.
Batshuayi said on chelseafc.com: "I am delighted to sign for one of the biggest clubs in Europe and embark on the next chapter in my career. I hope I can help Chelsea win many trophies during my time at Stamford Bridge.
"Eden Hazard and Thibaut Courtois have told me many good things about the club, and with Antonio Conte coming in it's an exciting time to become a Chelsea player.
"This is a fantastic opportunity for myself and my family, I am looking forward to playing in the Premier League next season."
Leicester have signed former France Under-21 midfielder Nampalys Mendy from Nice on a four-year deal.
The 24-year-old helped Nice secure a fourth-place finish in Ligue 1 last season and becomes the Foxes' third signing of the summer for an undisclosed fee.
