In the system Rodgers likes I'd say Gerrard still works very well in a deeper role. I agree back up is needed but it's not currently a major problem. Can maybe the back up.
I don't see us signing one while Gerrard is still going. I expect Can to be the back up.
I take your points, and perhaps, it willl work, but in the bigger games; much like in the UCL or in the big ties in the league City/Chelsea/Us (
) next season, Gerrard will need that defensive support to be at the level mandatory to deal with
top quality forwards and attackers. In the second half of one of the City games, I remember Gerrard struggling a little with the pace of the game and there wasn't anyone in your midfield to break up attackers to simply water carry the ball to Gerrard to instigate attacks.
Gerrard
Henderson --- Coutinho/Lallana
Is a little defensively lightweight, no? But it is a little bit out a catch 22 as you can't sign a pure defensive midfielder as he would struggle if he isn't playing the deepest (which Gerrard will be occupying). Perhaps I underestimate the defensive diligence of your midfield, or, perhaps the forwards will continue to compensate.
EDIT: I did forget Allen, who I quite like, but he again, is more of a complementary player who isn't the toughest defensively to screen and protect to back four.
