The majority of Carragher's England team-mates spent their day off either playing golf or with their families. Carragher opted to do a bit of homework on the opposition, watching all three matches, starting with Slovenia's defeat of England's next Group C opponents Algeria, and finishing with Germany's four-goal destruction of Australia.
It was a chastening experience given England's inability to overcome the United States 24 hours earlier, and placed even more emphasis on clinching top spot in order to avoid Joachim Low's men in the first knockout round. "They played so well last night that we are trying not to hype them up too much," he said. "
For the past eight years, Germany have appeared to be in the midst of a slump from which they have only just emerged thanks to Bayern Munich's charge to the UEFA Champions League final. But they have managed to reach a FIFA World Cup final and a semi-final in that time, while England's so-called 'Golden Generation' have lost at the quarter-final stage on two occasions.
Even now, Carragher does not feel England have an inferior squad, more that Germany may just have an unbreakable inner resolve that the Three Lions need to adopt. "Germany were very impressive. Joachim Low has done a great job and Mesut Ozil was outstanding. But you wouldn't say the names roll off the tongue," said Carragher.
"Maybe what they have is a belief of always being there at the end. It is similar to what we have at Liverpool where we are known for getting late goals no matter who is on the pitch. You believe you are going to do it. Maybe there is something in that because we [England] have not done very well in tournaments. But I am still pretty confident we can do well here."
In order to achieve success, Fabio Capello needs to resolve a number of issues, of which the identity of his goalkeeper for Friday's tussle with Algeria is one of the most pressing. Capello has already stated he needs to assess Robert Green's mental state before deciding whether to trust the West Ham stopper again.
Yet, on an individual basis, Carragher does not believe Green will find it difficult to raise his spirits after the first-half blunder that gifted the USA their equaliser on Saturday. "You do get knocked down in this game. Everybody does. But you have to get yourself back up again," said Carragher.
"I know people look at Premiership footballers and see the money and the lifestyle, but it has been a journey to get to that point. I scored two own goals in one game against Manchester United when I was 20. As a young kid it was hard to come back from that. But mentally, you have to be strong. I went to [the FA's former school of excellence] Lilleshall when I was 14-15. I wasn't better than the lads then but maybe my mentality helped me whereas some of the others might be playing non-league now."
The point is Green would not be where he is if he did not have the mentality to cope with the type of setback he experienced in Rustenburg on Saturday evening, without team-mates necessarily racing to his aid.
"Robert won't be feeling great at the moment but he will have done something when he was 16 or 17 where he needed to pick himself back up, then you get knocked down again and then you have to pick yourself up. That is why he is playing for England. And the best thing is he had a chance to rectify it, which he did by making a good save in the second half. In the last World Cup I missed a penalty. There was nothing I could do about that. I had to wait another four years."
