Rafael Benitez has no intention of letting Carson go however, and has told him to challenge Pepe Reina for a place in the Liverpool first team.
"I was speaking to Scott recently and I told him he will be part of our first-team squad next season," said Benitez.
"He must fight with Pepe Reina now for a starting place. We knew when we fought off Chelsea to sign him he was a talented goalkeeper.
"He got some good experience last season and now he is coming back to us."
