The hiring of Brendan Rodgers has large tactical implications for Liverpool.
In short, the old 4-2-3-1 is replaced by a modified 4-3-3.
The old system placed the striker off the formation up front. When Liverpool ran out of ideas under Dalglish, they punted it forward hoping to catch Carroll in the air. That style of play asks a lot and is a bit outdated.
Further, Carroll would go long spells without seeing the ball. As a result, his first touch suffered, and his confidence dipped.
Rodgers brings with him the Barcelona-style integrated approach.
In an interview via EPL Index, Rodgers describes the style:
When we have the football everybody’s a player. The difference with us is that when we have the ball we play with 11 men, other teams play with 10 and a goalkeeper.
Essentially, the new manager expects his striker to not only score, but also pass and create. He is purely the finisher; he is a link in the chain.
This approach should work for Carroll, whose vision and passing ability is vastly underrated. He should perform better given the increased time on the ball.
