Havertz joins fellow new arrivals Timo Werner, Hakim Ziyech, Xavier Mbuyamba, Malang Sarr, Ben Chilwell and Thiago Silva at Stamford Bridge.
Arsenal, meanwhile, have added Brazilian centre back Gabriel Magalhaes to their ranks.
The 22-year-old, who joins in £23m deal from Lille, said: “I spoke a lot with my family and my agents, I also spoke with some of Lille’s directors but, as I said, this club’s history and traditions and the team project for the next few years were very motivational for my decision to come here.”
