Chelsea just need to sign three more players in addition to Christopher Nkunku to build the perfect starting lineup for next season. The 25-year-old forward had been heavily linked with a move to Stamford Bridge for some time, but the Blues have finally announced his arrival from RB Leipzig.
Nkunku, who penned a six-year deal in west London, told the official Chelsea website: "I am incredibly happy to be joining Chelsea. A big effort was made to bring me to the club and I am looking forward to meeting my new coach and teammates 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."
