Sturridge has already scored twice in two games for the Reds.
"Daniel gave us a different dimension with real pace, playing on the shoulder, and every time he is on the box you sense he can get a goal," Rodgers said.
"Good players enjoy playing with each other and I think everyone recognises that, at 23, he has his best years ahead of him. You see him like he was against United and he is not even fully fit yet.
"He will be a real handful and, going forward he and some of the other players can be the real difference for us.
"It is important you have balance and for me that is the challenge, I want to have good players at the club and we will keep building our squad so we have that.
"But the players we are bringing in are flexible and can play in a couple of positions."
