The Germany international was linked with a number of heavyweight sides after scoring and assisting a combined 38 Bundesliga goals for Bayer Leverkusen in the past two campaigns.
Chelsea completed the club-record capture of Havertz in early September and the versatile forward has already made 10 appearances for his new side.
Real Madrid and Bayern Munich were among the sides credited with an interest in Havertz, but Chelsea ticked all the right boxes for him.
“To me, it was important to have a club with a vision,” he told Sport Bild. “The club is on the move. We are a young team with a lot of great players. We think aggressively.
“We want to build something here and attack. This motivates me. And then, a title with Chelsea is just worth more.
“A transfer like this doesn’t happen overnight. I had to go through all options and things which are important to me. I was watching a lot of Premier League on TV anyhow and knew Chelsea really well.”
Havertz has been directly involved in two Premier League goals in his first seven outings and has created eight chances from open play, a tally matched only by Reece James and Mason Mount among Chelsea players.
He is one of seven first-team signings made by Frank Lampard this year and says compatriot Timo Werner, another of the high-profile captures, has helped him settle into life in a new country.
“I help Timo with good passes on the pitch and, at the beginning, he helped me out with a lift to the training ground,” he said.
“We do a lot of things together. This helps a lot. But we also must go our own ways to fully settle here.
“To me, the move to England is also an important step for my personal development.”
Havertz is one of six different German players to have scored a Premier League goal for Chelsea, along with Werner, Antonio Rudiger, Andre Schurrle, Marko Marin and Michael Ballack.
