Carragher was delighted Gerrard was able to leave England duty to make a brief appearance.
"A big thank you to the people at the FA because it is not easy as they had two massive games - but I think it helped they won last night," he said.
"He is the best player I've ever played with so I'm delighted he was involved.
"England always have to do a warm-down the day after so that was his warm-down."
Gerrard felt it was important to play a part, however, small.
"Because I'm so close to Jamie, not just as a team-mate but as a friend, I wanted to be here to share it with him," said the England and Liverpool captain.
"I asked for permission to fly in and out and have a small cameo and he (Capello) was fine with it, although I'm sure his decision was based on beating Bulgaria 4-0."
