The striker has been linked with an exit in the summer transfer window.
The striker’s future has come under question in recent months, as he has found himself out of the starting line-up.
First he was dropped for the clashes against Borussia Dortmund in the Europa League as manager Jurgen Klopp opted for Divock Origi instead.
Then, with the Belgian out injured, he was left on the bench against Villarreal recently in arguably one of the club’s biggest games of the season.
That has led to talk that Klopp does not fancy Sturridge as his first choice and a sale may be imminent, but Murphy insists the Reds would not be able to replace him if they did.
“In terms of ability and goal scoring prowess, Sturridge is as good as Liverpool have got and he’s one of most talented strikers we’ve got in this country,” he told talkSPORT.
“His goals-to-games ratio for Liverpool is phenomenal and as a striker, what do you do? You score goals! Goals win games and Sturridge is the best striker Liverpool have got.
“The bottom line is, can Liverpool sell Daniel Sturridge and use that money to get someone better? I don’t think they can.”
There is no denying that there would be a long line of clubs interested in Sturridge should Liverpool decide to sell this summer.
He would drastically improve a number of sides and indeed that may be something that will see the club rule out a sale.
Liverpool would be loathe to sanction a sale and see the move come back to haunt them, although whether Sturridge is happy to sit on the bench in future is debatable.
