Central defender moves to the Premier League champions from Serie A side Roma.
Germany defender Antonio Rudiger 'very proud' after completing Chelsea switch
Premier League champions Chelsea have completed the signing of Roma defender Antonio Rudiger on a five-year contract.
Rudiger, a 24-year-old Germany international, has moved to Chelsea in a deal reported to be worth £34 million (Dh161m).
Rudiger becomes Chelsea's second first-team signing of the summer after goalkeeper Willy Caballero.
"It's a great feeling because not every player has the opportunity to join a huge club like this," Rudiger said.
"I am looking forward to meeting up with my new teammates and I'm very proud to officially become a Chelsea player."
Rudiger began his career at German club Stuttgart before moving to Roma in 2015, where he helped the club to second-place in Serie A last season.
Most recently, Rudiger was part of the Germany team that won the 2017 Confederations Cup in Russia.
"We are pleased to be able to bring in a player of proven quality who adds to our defensive options," Chelsea technical director Michael Emenalo said.
"Antonio is still young but is experienced at club and international level and possesses all the requisite attributes to thrive in the Premier League. We have been aware of him for some time and we are confident he will fit in well with the squad."
