Thomas Tuchel has part ways with Borussia Dortmund after only two years in charge of the Germany Bundesliga side.
Tuchel joined the club in 2015 after the departure of Jurgen Klopp who has since joined Liverpool in the English Premier League.
The 43-year-old leaves just days after Dortmund beat Eintracht Frankfurt by 2-1 to win the German Cup on Saturday. He also guided the club to a third-place finish in the Bundesliga to qualify for next season’s UEFA Champions League.
Tuchel said in a tweet on an official Twitter account: "I am grateful for two exciting, beautiful and eventful years. It's a pity to not go on. Thank you to the fans, the team, the staff and to all who have supported us."
Meanwhile, Luciano Spalletti has also left Italian giants AS Roma after guiding the club to a second place finish in the Serie A and a direct qualification to the champions league.
"We would like to thank Spalletti for his hard work and his significant contribution since his return," said Roma President Jim Pallotta.
"Under his stewardship this season, the team has won more Serie A points and scored more goals than any side in Roma's history. We wish Luciano all the best for the future. This club is on a constant path of growth and that will continue with the appointment of a new coach who shares our values and philosophy and who will continue to help us take AS Roma forward," he added.
The 58-year-old returned to Roma for the second stint in January 2016. He first coached the club between 2005 and 2009, winning the Coppa Italia twice before throwing in the towel. He later joined Zenti St Petersburg in Russia.
