Chelsea have completed the signing of Roma defender Antonio Rudiger on a five-year contract.
The 24-year-old Germany international will cost the Stamford Bridge club an initial £29million with add-ons potentially taking the deal to £33.3m.
Rudiger will take over the number two shirt left vacant after Branislav Ivanovic’s departure to Zenit St Petersburg in February.
The German defender becomes the Blues’ second major signing of the summer after the arrival Manchester City goalkeeper Willy Caballero.
Rudiger, 24, completed the transfer one week after helping world champions Germany win the Confederations Cup.
The defender said: “It’s a great feeling because not every player has the opportunity to join a huge club like this.
“I am looking forward to meeting up with my new team-mates and I’m very proud to officially become a Chelsea player.”
Rudiger has spent the last two seasons in Serie A, joining Roma on loan at the start of the 2015-16 season and then joining the club on a permanent basis last summer for £7.6m.
“Antonio is still young but is experienced at club and international level and possesses all the requisite attributes to thrive in the Premier League,” said Chelsea’s technical director Michael Emenalo.
“He is a player of proven quality.”
Rudiger played for Borussia Dortmund at youth level before moving to Stuttgart in 2011.
He made his Bundesliga debut in January 2012 and clocked up 66 appearances in Germany’s top flight before moving to Roma in 2015.
Rudiger made 30 Serie A appearances in 2015-16 as Roma finished third and a further 26 in 2016-17 as they were runners-up to Juventus.
He also played six Champions League games in 2015-16 as Roma reached the last 16.
In addition, Rudiger has made 17 appearances for Germany, including a 1-0 win friendly win over Englandin March, but was ruled out of Euro 2016after tearing cruciate knee ligaments.
Because he was set to take a break after his involvement in the Confederations Cup, Rudiger is unlikely to be involved when the majority of Antonio Conte’s squad return to pre-season training on Monday.
