Reina, Johnson, Skrtel, Agger, Jose Enrique, Lucas, Gerrard, Suarez are the main players in the squad and should stay bar anything extraordinary happens.
Henderson, and Carroll would stay too. Henderson is a pass and move player and could thrive under Brendan.
Think we might keep Craig, Maxi and Dirk as well, Maxi is a perfect pass and move player but it would also depend on him, it was reported he wanted to go back to Argentina so you never know. Dirk with his energy and commitment may stay as well.
Aquilani? Maybe finally he could make an impact with the club? The lad has talent and the kind of football philosophy Brendan follows, he can be a good fit. But considering how he has been ignored in the past, won't bet on it.
Kelly and Coates are young players and would definitely keep their places. In fact Coates might become the 3rd choice CB.
Sterling, and Shelvey are promising youngsters and considering Brendan's youth coach background he could very well be ease on the transitions of Sterling and Shelvey.
Spearing and Doni should make it simply as squad players.
Charlie Adam, Stewart Downing, and Jamie Carragher are the ones I am not sure whether they would be pass and move type of players. Think they would be sold or kept nothing more than squad players.
Again all of this is just my opinion and my perception of how Brendan Rodgers might look at the current squad, so pinch of salt and all that.
