Liverpool have confirmed their squad for the group stages of the Champions League.
Whilst there are not many surprises in the 24 names listed, there was no room for rising star Curtis Jones.
That is despite some good performances from the Liverpool midfielder so far this season.
Yet clubs have only submitted a List A squad for the Champions League.
UEFA rules state that clubs must submit two lists of players for their Champions League registration.
The first one, List A, is the squad list that was submitted this week and contains a number of rules.
These include having a minimum of eight places for locally trained players - although the maximum number of players in their squad is reduced should these numbers not be met.
Locally trained means players that have been trained by their club or another club in the same nation for at least three years between the age of 15 and 21.
Four of these players must have been trained at the club they are being registered for.
Younger players, however, do not need to be registered on List A.
Instead, there is a List B for players born in 1999 or after who have been eligible to play for their club for at least two years since their 15th birthday.
That means Jones, who was born in 2001 did not need to be registered in the Reds' main squad.
There are no limits to the amount of players that can be registered on a List B, provided they meet the eligibility criteria.
That means the likes of Neco Williams and Rhys Williams will likely also be included on the list.
Whilst Harvey Elliott is young enough to be included on List B, he has had to be named on List A due to the fact it was only a year ago he moved to Anfield.
