Fernando Torres is being painted as the final piece in Liverpool's jigsaw - a puzzle that remains incomplete after 17 title-free years at Anfield.
"The final piece of the jigsaw" is a phrase that has become synonymous with Liverpool in an era when they have failed to win the trophy they covet most.
The pieces have been assembled by a succession of managers, only for men like Graeme Souness, Roy Evans and latterly Gerard Houllier to find another crucial bit had gone astray.
Boss Benitez has suffered a similar fate, despite successes in the Champions League and the FA Cup.
The list is endless - Paul Ince, Stan Collymore, Harry Kewell and Djibril Cisse to name but a few.
Now Torres is poised to take on the cursed mantle, complete with a huge £26.5m transfer fee and a lavish six-year contact to match.
The 23-year-old Spain striker will be under pressure to deliver - but this deal has as much riding on it for Benitez as it has for Liverpool.
Benitez has cited a lack of funds and an inability to compete for A-list stars as reasons for his failure to get anywhere near the Premiership pace-setters.
He made his most pointed accusations in what appeared to be a fit of pique after the Champions League final defeat against AC Milan in Athens in May.
It is a claim which will draw gales of laughter from some clubs, given the scale of investment handed to him by Liverpool's board in the last three seasons - much of it spent on very ordinary players.
It is also a claim he can never make again - not when new owners George Gillett and Tom Hicks have broken Liverpool's transfer record in such emphatic style.
The arrival of Torres is as much a defining test of Benitez's title credentials as it is of the young Spanish striker's glowing reputation.
There can be no more excuses if they fail to threaten Manchester United and Chelsea this season.
Torres is A-list and expensive; a symbol of the sort of player Benitez claims has been out of his reach before.
Now he has got him, bought and paid for in a record-breaking manner, he can no longer use finance as his shield against expectations.
And yet, despite his undoubted quality, Torres comes with an element of risk as well as an expensive price tag.
He is powerful, athletic, proven in Spain, if not beyond, and able to play as a lone striker as well as in a partnership.
But he is untested in the Premier League and is so costly that inevitably huge pressure will be placed upon him.
Benitez must hope he does not suffer the same fate as Fernando Morientes, who arrived at Anfield amid much fanfare.
He was a failure, skulking back to Spain quick-smart complaining that defenders in the top flight had the affrontery to tackle him. And tackle him quite hard.
Torres is the identikit of the sort of player Liverpool need to add to a miserly defence and an array of midfield talent.
If he comes off he could actually be, well, the last piece of the jigsaw.
Liverpool lost points and games they should have won last season because they were essentially a blunt instrument in attack.
Craig Bellamy has not been up to the job and, while Dirk Kuyt may have a heart as big as a bucket, he is hardly ruthless operator in front of goal.
Peter Crouch remains Liverpool's most reliable striker, but Benitez would not trust him with a starting place in the Champions League final.
Torres must come up with the goals his price tag demands - and this is because the stakes are as high for Benitez as they are for Liverpool.
