London - England international Gary Cahill has signed a new four-year contract with Chelsea, the Premier League champions announced on Wednesday.
The deal will keep the 29-year-old defender at Stamford Bridge until 2019.

"I have achieved a lot here and I hope I can keep on learning, helping the team and lifting trophies over the next four years," the defender added.
