Christopher Nkunku has been introduced as the new Chelsea signing, over 8 months following secret medical testing.
The footballer has agreed to a six-year contract extension with Chelsea until June 2029.
Chelsea paid a sum of around €60 million 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 has 16 goals and six assists in 25 Bundesliga matches this season, can play both as a center striker and as a No. 10 defender.
“Christopher has proven 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,” said Chelsea’s co-sporting directors Laurence Stewart and Paul Winstanley.
Nkunku is Chelsea’s second signing of the summer, following the €20 million (£17.27 million) acquisition of Ecuadorian midfielder Kendry Paez from Independiente del Valle. He won’t be able to join the club until he is 18 in 2025.
Nkunku was one of the players Real Madrid wanted to bring in to bolster the assault, but it was too late.
