He may have retired from competitive duty in May, but Jamie Carragher was determined to maintain Liverpool's clean sheet record this summer when he played 30 minutes of Steven Gerrard's testimonial on Saturday.

Brendan Rodgers' team have claimed five victories from five pre-season fixtures so far in their preparation for the 2013-14 campaign, and all without conceding a single goal along the way.

Having kept visitors Olympiacos at bay for an hour at Anfield, Rodgers introduced Carragher to the backline in place of Kolo Toure - and the 35-year-old was as conscious as ever of the necessity for defensive concentration.

"I came in yesterday and was disappointed I wasn't starting!" Carragher told LFC TV after the final whistle.

"But it was great to come in and train with the lads. There are a few new players as well, they have bedded in well.

"I think the pre-season has gone well, I've been watching all the games on LFC TV. They are looking good and hopefully we'll start the season well.

"From an offensive point of view they have scored a few goals. I was just a bit worried I was going to come on and we were going to concede, because I know they haven't conceded in pre-season yet.

"If you get those two things right, you're doing well. We want to get plenty of goals - we've still got Sturridge to come back, Luis is just getting back into it, I think the manager is looking to bring another attacking player in, and Robbie as well!"

Barely three months have passed since Carragher was the centre of Anfield attention, when he played his 737th and final match for the Reds against Queens Park Rangers.

Ever the model professional, the defender was keen to feature in his good friend's testimonial but equally aware of the fixture's importance on the side's road to beginning the season.

He added: "It was important, but it was always down to Stevie and the manager really because it's an important pre-season game before the start.

"You don't really want to get too involved because you realise it's an important game in itself. But they asked us to be involved and we were pleased to do so.

"It was just nice to be involved in a great occasion for Stevie, his family and friends. We're friends as well, never mind teammates. It was just nice for Stevie and the manager to ask us to be involved."
