"I am devastated for Michael. He is a good friend of mine and he thinks it might be a long term injury but Crouchy is up to the task of stepping in," said Carragher.
"His record for England proves that over the last six or seven games. He has got a goal a game in that time. His record stands up with any striker in the world over the last few games.
"To get the goals he has done, even the best strikers in the world would struggle to achieve that ratio. I've got confidence in him.
"He has done superbly recently and that's all you can do with England. I'll be pleased if he carries on doing well because he has received a lot of criticism this season after not scoring early doors for Liverpool and then some people gave him stick with England. But he has proved everyone wrong and I have faith in him."
