Almost 8 months after secret medical tests, Christopher Nkunku has been unveiled as new Chelsea signing.
The player has signed a six-year deal with Chelsea which is valid until June 2029.
Chelsea paid transfer fee close to €60m to RB Leipzig.
“I am incredibly happy to be joining Chelsea,” said Nkunku, who came through the Paris Saint-Germain youth system.
“A big effort was made to bring me to the club and I am looking forward to meeting my new coach and team-mates and showing the Chelsea supporters what I can do on the pitch.
“Having played in Ligue 1 and the Bundesliga, I now want to play in the Premier League, one of the strongest leagues in the world. I am very excited for this challenge and will be proud to wear the Chelsea shirt.”
Nkunku, who scored 16 goals and provided six assists in 25 Bundesliga appearances this season, can play as a centre forward and in the No 10 position.
Laurence Stewart and Paul Winstanley, Chelsea’s co-sporting directors, said: “Christopher has proved himself one of the standout attacking players in European football over the past two seasons and will add quality, creativity and versatility to our squad.
Nkunku is Chelsea’s second signing of the summer after the transfer of 16-year-old Ecuadorian midfielder Kendry Paez from Independiente del Valle for €20m (£17.27m). He will not join the club until 2025, when he turns 18.
Nkunku was one of the players Real Madrid liked the most to reinforce the attack but they were too late.
