Paris St Germain have announced the appointment of Thomas Tuchel as their new coach.

The German, who has been out of work since leaving Borussia Dortmund last summer, will succeed Unai Emery at the Ligue 1 champions.

Emery's two-year spell in charge at the Parc des Princes will come to an end after PSG's final game of the season at Caen on Saturday. 

The highly-rated Tuchel has signed a two-year contract in the French capital.

The 44-year-old was appointed at Jurgen Klopp's successor at Dortmund in 2015 and won the DFB-Pokal last season, but left after falling out with the club hierarchy.

Before Dortmund Tuchel was in charge of Mainz for five years.

He will be tasked with turning big-spending PSG into a side capable of winning the Champions League.

Emery's side won the domestic treble this season, but went out of the Champions League in the last 16 to Real Madrid. 

"It is with great joy, pride and ambition that I join this great world football club that is Paris St Germain," Tuchel said on the club website.

"I look forward to working with all these great players, all of whom are among the best on the planet.

"Together with my staff we will do everything to help the team push their limits to the highest international level.

"There is extraordinary potential in Paris and this is the most exciting challenge that I have received.

"I am also looking forward to experiencing the Parc des Princes, a legendary European football stadium with a fantastic atmosphere."
