Alonso said on Chelsea's official website: "I am so happy to stay here longer and to keep playing for one of the best teams in the world.

Chelsea director Marina Granovskaia added: "We are delighted to be extending Marcos' contract.

"In the past two seasons he has developed into an important player for the club, demonstrating his outstanding ability and a fantastic attitude that has helped him become a Premier League champion and Spain international."
