Liverpool skipper Steven Gerrard says he could retire from football as young as 33 years old when his current contract expires in 2013.

Gerrard, who made his debut for the club in 1998 under Gerard Houllier, also says he is proud that he has spent his whole career at Anfield, including rejecting a move to Chelsea in 2005.

“I will be 33 at the end of my contract in 2013 and I don’t know if I will go any further,” Gerrard told France Football.

“If I do retire, then I will know that from the start to the end of my career I only had one club. And I don’t want to think about wearing any other shirt in the future.

“I was close to leaving in the past, maybe twice, most notably in 2005. That year we (Liverpool) were a long way off the Premier League title and Chelsea’s interest turned my head.

“It was a difficult moment for me. However, now when I look back I am very happy that I chose to stay here. It has given me real pride.”
