Sturridge is in line for a start this weekend against Newcastle United.
Rodgers said: "He was outstanding when he came on. In the first half of the game we were too slow in our play, our movements weren't as dynamic as what they've been in a lot of games.
"The intensity in our game wasn't quite what it normally would have been. In the second half when he came on, he gave us a real threat - his pace and power were outstanding. He scored a goal which was a great finish and could have had two or three more.
"He's fitted into the football club really well. He missed a bit of training last week but if we can keep him fit and keep him out on the training field, he's got the potential to be a top European striker and that's hopefully something he can fulfil here at the club."
