Chelsea have announced the signing of Belgium forward Michy Batshuayi from Marseille.
The 22-year-old, who had also been linked with a move to Tottenham Hotspur and Crystal Palace, has signed a five-year contract with the Blues after returning from international duty at Euro 2016.
It is understood that the striker has cost Chelsea in the region of £33.2m.
"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," he told the club's official website.
"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."
Batshuayi hit 17 Ligue 1 goals during the 2015-16 campaign.
