The reserve team captain was Liverpool's best player in their 1-1 draw in the FA Cup third round tie at Reading yesterday and his performance earned him the praise of Carragher.
"He played very well and I'm really pleased for him," said the vice captain.
"I thought he also did well against Fiorentina recently, and he was just unfortunate at the end of that game with the mistake.
"It wasn't the easiest game against Reading, and it was very difficult to play in, but he showed great character to come back from it.
"It was great for him and you also have to give credit to the manager for picking him.
"It would have been easy [not to pick him] after what happened against Fiorentina, but if you look at that game he was one of our best players on the night.
"And he was superb against Reading, which shows that he's not only just a good player, but also has very strong character.
"He was a very composed in a tough game. Sometimes it's easier to play well when the team plays well, but to come through it and perform well at a very difficult place to play can be a real battle and we're all pleased for him because he's such a nice lad."
