``I've played in different positions. That's modern football, with big squads, injuries and suspensions. You've got to be able to adapt. Our manager at Liverpool switches the team around.

``I can go back to getting my chance in the Liverpool youth team when we won the FA Youth Cup to play at centre-half after someone got injured and it went on from there.

``It was the same with getting a chance in the first team at left-back. We had three or four injured for a game against Newcastle and Steve Staunton was going to play but then also had to pull out.

``I played in there and from then on we started keeping a lot of clean sheets and that convinced the manager in the end that I could play there. I've played in a few positions.

``My best positions? You tell me. Being in the first XI is what counts. There are internationals on the bench who have done more than me, like Jari Litmanen who won the European Cup with Ajax.

``A lot of people have been bought in the positions I've been in but I've always stayed involved.

``But I don't know if myself being versatile will help me to get into the World Cup 22. It could or it couldn't.

``I would have thought with 22 players you would have most positions covered, but I suppose it could give you the possibility of more options in another position if someone can move around.

``I've been in a few squads and we'll have to see whether it aids me or not. I think at club level it is a big advantage being versatile but at international level it might be a bit different.

``I think it has helped me to get on the bench with playing in a few positions so that from that side of things it has been a plus factor. I'll play anywhere to get a game. It's an honour to me when I get a cap.''

Carragher insisted that though Saturday's game is a friendly, there is still much at stake for England's players. He explained: ``There are four or five games before the World Cup and I don't think anyone will be resting on their laurels.

``You have to try and impress the manager whether it's in a training session or in a match situation. All the lads here are desperate to be part of the squad.

``You have got to take every chance, even if it is only for 10 minutes at the end of a game, to show the manager you are capable of doing the job.''
