"I'm very happy," said the Liverpool skipper. "It's a very proud day for myself and my family.
"It comes on the back of a fantastic team performance last night when we got the result we were looking for. Hopefully we can finish the job off in two weeks time and take all of our magnificent fans down to Wembley for a day out.
"The contract extension coming the day after has been the icing on the cake so it has been a perfect 24 hours.
"It's really flattering for me that the club have offered me the chance to stay when I eventually hang my boots up," he added. "Hopefully that will be in many years to come because I want to play for as long as I can."
