The 35-year old defender made his 737th and final appearance for the Reds in their 1-0 win over QPR at Anfield on Sunday and said it was a sensitive issue as he bowed out of the game as a winner in front of appreciative home fans.
"It was very emotional, especially for my friends and family in the stands who have been there to watch me all the time, but that's come to an end now unfortunately," said Carragher.
"I think the club is in good hands, we've had a good run in the second half of the season and hopefully can go from strength to strength.
"I wanted to say thank you to the supporters as that was important. It was a game we wanted to win and it was nice for my children to be involved.
"There wouldn't have been anything worse than going out with a defeat today or a poor performance that would have nagged away at me so it was just nice to keep a clean sheet and win the game."
