Liverpool boss Brendan Rodgers will have to dip into his U21 squad to cover the absence of Fabio Borini.
Borini is out for three months with a fractured foot.
German youth international Samed Yesil could be promoted, having made his debut as a substitute in the Capital One Cup last month, but Rodgers said throwing in youngsters was not always the best option.
"We have other players that we may be able to have some flexibility within the team," he said.
"It is great for me to see the young players: Adam Morgan scored a couple of excellent goals for the reserves and Samed Yesil is a goalscorer.
"It is just a case of weighing up whether they come in or not.
"Not every young player can play: this is an unforgiving league and my job is to nurture the talent and not destroy it."
