A product of the Liverpool academy, he made his only senior appearance for Liverpool in the FA Cup in the 2019/20 season.
He was a regular for their Under-23 side in Premier League 2 last season and is considered a bright prospect on Merseyside.
Liverpool have been looking to find a club for him to go out on loan to this season as they want him to play regular senior minutes to speed his development.
And it has been claimed that an agreement is in place for Cain to join Newport County in League Two on loan on deadline day today.
The two clubs are finalising the agreement for the 19-year-old to move to the League Two club on loan for the season.
The teenager will soon undergo medical and complete the formalities of his loan move to Newport County.
Cain will hope to play regular first-team minutes in the fourth tier of English football before returning to Liverpool next year.
