The Germany international has said that he spoke to a number of clubs before he signed for Chelsea earlier this summer.
The 24-year-old striker moved to the Blues from RB Leipzig in June on a five-year contract for a transfer fee of 45 million pounds.
Werner told Sky Sports: “Yes, I think when I decided to leave Leipzig, I talked to different clubs and next to Chelsea, I spoke to other clubs. For me, I don’t want to talk too much about other clubs.
“Of course, there are some other clubs like Liverpool who have a great team. Maybe I could fit in other teams but, in the end, I decided Chelsea because it was the best decision I could take. Not only the style of football but because of what they showed me.
“Yes, it was a hard decision in the end but I am very excited, proud and happy that I decided this. Now I am here for maybe two months, and it feels right, good and the team is brilliant. We have some very good but calm and nice players.
“It is fun to play at Chelsea, be part of the team and be part of what we start here. We can do very well with this team in the next few months and years.”
