Steven Gerrard could extend his Liverpool career by becoming a ball-playing centre-back, according to manager Brendan Rodgers.
Gerrard, 33, has remained an influential midfielder at Anfield since making his first-team debut in 1998, but faces a couple of major decisions about his long-term future over the next two years.
The England captain is set to consider whether to retire from international football after next summer's World Cup finals in Brazil. And he will then have to decide whether to extend a Liverpool contract, signed last summer, that expires in 2015.
Rodgers indicated earlier this month that he felt Gerrard would quit the England set-up after the World Cup, although the player himself has said that he still needs to talk to the people around him before making a decision.
Manchester United midfielder Ryan Giggs turned 40 on Friday, but Rodgers believes Gerrard's longevity will be dictated by his fitness. The Liverpool manager said: "He will be 34 at the end of this season, and I look at his fitness and I think he's as fit as he's ever been.
"He's looking after himself. Of course, that player that he maybe was 10 years ago, being dynamic and making those lung-bursting runs, that goes out of your game. I look at Steven and I think he can play as a number two centre-half later in his career.
"You play against certain teams who've got one up front, and I think he can play against them as a right-sided centre-half and build the game from behind. The way he passes the ball is as good as anyone in the world, short and long. It's a possibility that he could go on. But it will always be determined on fitness."
