Carra takes warning from history
You don't need to warn Jamie Carragher about the dangers of giant-killings.
He has been there, done it and been asked at the end of 90 minutes to swap t-shirts with players from the lower league who'll never forget their victory over Liverpool.
In the last 13 years in the FA Cup the Reds have succumbed to lower-league opposition on five occasions - Blackburn (2000), Crystal Palace (2003), Burnley (2005), Barnsley (2008) and Reading (2010).
But as Brendan Rodgers' side prepare to travel to Blue Square Premier League outfit Mansfield in the third round on Sunday, another match will be at the forefront of Carragher's mind.
Though Liverpool were ultimately victorious against Havant and Waterlooville in 2007-08, the non-league side put up quite a fight.
"I was thinking about Havant and Waterlooville when we were 1-0 down and 2-1 down at Anfield," Carragher told Liverpoolfc.com. "That shows you how difficult it can be. No matter who you are playing against you can get caught out.
"That game was at Anfield, so this is going to be even more difficult.
"It will be one of the biggest games of their lives on Sunday but it should be for some of the Liverpool players - I always play every game as if I don't know if I'm going to get another.
"I haven't started many games this season and hopefully I'll be starting - players should look at it like that and try to show the manager what they can do."
Carragher is a two-times winner of the FA Cup and, though he accepts the competition's importance has been diminished in recent years, he is a big fan.
"I grew up with the FA Cup," said the 34-year-old. "Its importance has maybe diminished slightly because of how big the Premier League has become and how big the Champions League has become.
"But third round day is a great day. The minnows against the big clubs, loads of different ties.
"The giant killings were fantastic moments, if you weren't on the end of them! I remember Arsenal losing at Wrexham, that was a big one. I think they were the champions.
"You look at it and you hope the smaller teams will do well, but you don't want it to be against you.
"This is a great draw for everyone, a great draw for Mansfield being on TV, and it's what the FA Cup is about.
"Obviously we should win, of course we should win, but it will be a difficult game and an eye-opener for some of the players.
"We should have enough quality. If we have the right attitude and the players are focused and ready then we should come through it unscathed."
One difficulty for the players on Sunday will be the Field Mill pitch, which was unfit for use last weekend resulting in the postponement of Mansfield's match with Grimsby.
Carragher is not planning to use the conditions as an excuse should there be an upset.
"That's what you have to deal with," he said ahead of what could be his 40th FA Cup appearance.
"It's the same for both teams. People talk about the pitch but we all grew up playing on pitches like that as kids. It's not ideal but you've got to get on with it and find a way to win."
Liverpool could deploy new signing Daniel Sturridge at Field Mill, and Carragher has let it be known that he thinks the former Chelsea man will be an asset whenever he eventually earns a debut.
"I think it's a good move," he said. "He adds a bit of strength and pace, something that we've maybe lacked at times this season. And he gets a goal.
"He can play in two or three positions and gives us a bit more cover for Luis.
"He did really well at Bolton. I remember him coming off the right wing onto his left foot and getting a lot of goals there.
"He is young-ish, and the price-tag and the whole package looks like a good deal for us."
A veteran of 719 games for Liverpool, Carragher passed another landmark on Wednesday when he overtook Billy Liddell to become the club's second highest appearance holder in the league behind Ian Callaghan.
His current tally is 493 and he already has another milestone in his sights.
"I was aware of it," he said. "Every game you get closer to something and someone mentions it.
"Billy Liddell was like Steven Gerrard in the 1950s. I can't say I've seen him too much as a player, obviously, but it was Liddellpool then, wasn't it? That shows how highly he was regarded.
"Getting to that 500 games in the Premier League - there are not many [players who've done that]. Hopefully I can do that."
