Chelsea have made their first major signing of the summer with the arrival of Roma defender Antonio Rudiger on a five-year contract.

The 24-year-old Germany international will reportedly 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.

“It’s a great feeling because not every player has the opportunity to join a huge club like this,” the defender, who was a member of Germany’s victorious Confederations Cup-winning team last weekend, told chelseafc.com.

“I am looking forward to meeting up with my new team-mates and I’m very proud to officially become a Chelsea player.”

Chelsea’s only other signing so far this summer is Manchester City’s out-of-contract goalkeeper Willy Caballero.
