The former midfielder has likened him to the Chelsea legend, while saying Liverpool's hopes rest entirely on the Belgian's shoulders.
The giant Belgian is one of a number of new faces at Anfield this summer, with Brendan Rodgers having invested heavily as the Reds aim to get back into the Champions League once again.
Benteke arrived in a big money move from Aston Villa with the remit of scoring the goals they need next season, after the side particularly struggled up front last season.
And Souness says Liverpool’s hopes for the season rest entirely on his shoulders.
“For me, for Liverpool to have a great season Benteke has to play the vast majority of the games and be scoring nearly every week,” he told Sky Sports Super Sunday.
“That’s a must for me if they’re looking to get into the Champions League positions. I think Benteke has to have a great season to fire them in there. There’s so much riding on his shoulders.”
Souness though, is certain that Benteke is more than capable of coping with the pressure now on his shoulders at Liverpool.
The Belgian is arguably used to being expected to perform week in week out having been Villa’s star man during his time there, with him being their stand out performer when it came to getting the goals.
And Souness says when he is on form he is akin to former Chelsea star Didier Drogba, but he must be on form every week from now on.
“Is he capable of it, he most certainly is,” he added.
“A Benteke on fire borders on unplayable, he’s the nearest to Didier Drogba was in his heyday, but there’s also the Benteke who appears uninterested. He cannot pick and choose whether he gives it everything now.”
A change of style
What will certainly be interesting to see is if Benteke can adapt his style to fit that of Liverpool.
Both Tim Sherwood and Paul Lambert before him used the forward’s power in the air to their strength, with them often relying on crosses to provide him with the ammunition.
Liverpool aren’t known for their crossing though, and instead try to pass more, meaning Benteke will have to adapt his game to suit Liverpool’s style. Perhaps
