The former defender believes that the striker needs to be 100% mentally and physically for Liverpool to see his best.
The striker missed the majority of last season through an injury he picked up on international duty with England, while he has also missed the start of this season as he recovered from surgery this summer.
He is nearing full fitness once again though, and showed his goal scoring touch in the 3-2 win over Aston Villa on Saturday as he scored two of his sides goals to help them to victory.
Lawrenson though, says the outwardly confident star will have been questioning himself before the game.
“I can guarantee Sturridge will have been second-guessing himself when he stepped on to the field against Aston Villa,” he told the Liverpool Echo.
“He’ll have been asking himself whether he can still do it, whether his fitness could hold up, having not long been working again the main group. Two goals later – and brilliantly taken they were too – and Sturridge will be flying.”

And Lawrenson believes that confidence is a massive part of the striker’s game, possibly more than it is for other players.
Much has been made of Sturridge’s injury record over the years, with it being evident that the player has the quality to be a top forward, but often being curtailed by niggling injuries.
It is obviously something that must play on his mind, and Lawrenson believes that to get the best from him, he must be 100% in both mind and body.
“Confidence is always a big thing in football,” he added.
“But I would say that for Sturridge, it’s a massive, massive part of his game. You get the feeling that to get the best from the striker, he has to be 100% right in both body and mind.”
