Timo Werner claimed during his German national team press conference that he imagined his time at Chelsea would turn out differently.
The 26-year-old was granted a permanent departure from Les Bleus this summer, after falling out with former manager Thomas Tuchel.
He was signed by RB Leipzig, setting up a reunion with his former side where he started the campaign well.
The striker is one of several players to have reportedly fallen out with Tuchel over the summer, although he was the only one granted a permanent switch.
Christian Pulisic and Hakim Ziyech failed in their efforts to get away from the club, while Callum Hudson-Odoi was only allowed to leave on loan.
Werner unhappy with Chelsea time
Although Werner certainly had a great time in west London, he said the overall experience was not what he expected.
He said: “For me personally it wasn’t the best time. I imagined it would turn out differently. I learned a lot and won the Champions League and other cups. I enjoyed both years abroad – and I really enjoyed London. I had mixed emotions when I left.
“In Leipzig, in the first few weeks, not everything went perfectly, but the new coach’s style of football suits me very well and prepares me for what will be required in the national team.”
The 26-year-old will look to wait or strike up a relationship with current Blue Kai Havertz on the international stage, without him enjoying the best personal start to the season.
With the World Cup just months away, it was important for Werner to have first-team football under his belt to put him in the best position to be picked by Hansi Flick at the start of the tournament.
