Gary Cahill signs new four-year Chelsea deal despite John Stones transfer speculation

Gary Cahill has put pen to paper on a new deal that will keep him at Chelsea until the summer of 2019. The 29-year-old defender has committed his future to the club amid a backdrop of uncertainty over the centre-back position in Jose Mourinho's ranks since summer links with Everton's John Stones.

Mourinho currently has Cahill, John Terry, Kurt Zouma and Papy Djilobodji at his disposal. He also signed Michael Hector from Reading on the final day of the summer transfer window, before loaning him back to the Championship outfit for the rest of the season.

Terry's future at the club is uncertain. His current deal expires in the summer as Chelsea operate a policy of offering players over the age of 30 one-year contract extensions only. Djilobodji is expected to leave in the January window after failing to convince since his surprising summer arrival from Nantes.

Daily Mail recently reported Chelsea were ready to return with a fresh bid for Stones after three separate bids were rejected over the summer – including one of £30m ($44m).

Meanwhile, the Blues have tied Cahill to the club until 2019. The England international and Zouma are the only current centre-backs who appear to have a secured future in West London.

"Chelsea Football Club is delighted to announce Gary has signed a new four-year contract, keeping him at Stamford Bridge until 2019," the clubconfirmed.

Cahill said: "I'm really pleased to commit my future to Chelsea and it's great the club has put their faith in me. 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."
