Midfielder Eden Hazard says Chelsea can win more than one trophy this season.
One of the most important players in Jose Mourinho's side, the 24-year-old has signed a new five-and-a-half-year deal with the Blues.
The Belgium international was a £32m signing from Lille during the 2012 summer transfer window and has scored 43 goals for the Blues in 147 appearances.
"I am very happy to sign a new contract with Chelsea," Hazard told the club's official website.
"Since I came here in 2012 I have always felt good and the club has been very supportive to me.
"The manager has helped me improve a lot, the fans have been fantastic and I have an amazing understanding with my team-mates.
"I always try to give pleasure to the supporters with my style of play and it is nice to know they appreciate my work.
"I hope we can repay that support by winning lots of trophies, beginning with the Capital One Cup at Wembley, and after that, we can push hard towards the end of the season."
