Almost from day one of Jurgen Klopp's Liverpool reign, Roberto Firmino was being asked to reinvent himself.
Arriving from Hoffenheim in the summer of 2015, the Brazil international joined to be an attacking midfielder under Brendan Rodgers but found himself being thrust further forward once Klopp had got his feet under the table at Anfield in October.
The term 'false nine' was subsequently bandied about as supporters became adjusted to a new type of centre-forward at the club; one whose overall output outweighed a fairly modest goal return by some of the legendary strikers' standards of years gone by.
Just about making it to double figures in the Premier League in his first season, his 10-goal return was fairly ordinary for a Liverpool striker when viewed solely in that particular prism, but Firmino's importance to the cause was growing as Klopp's revolution gathered pace.
As Firmino continued to evolve as a No.9 at Anfield, he would become the foil for Sadio Mane and Mohamed Salah as the trio - who would collectively become affectionately known as 'the front three' - blasted in 91 goals between them in the 2017/18 campaign.
But after changing himself from a creative midfielder to someone who added a fresh twist on the classic No.9 role, Firmino is once again seemingly being asked to transform himself under Klopp.

The arrival and adaptation of Diogo Jota gave Firmino competition like never before at Liverpool and the Portugal international has arguably replaced the 30-year-old in the team under Klopp this season.
His 19-goal return is only outscored by Salah and while he offers a very different kind of threat to Firmino's beguiling, unselfish style, Jota can now justifiably lay claim to being part of Liverpool's strongest 11.
“Oh what a player! What a boy!" says Klopp of the former Wolves man.
Luis Diaz's January move from Porto has only increased the competition at Anfield as Klopp now surveys what is surely the strongest set of forward options in the Premier League era.
The Colombian hasn't taken much time to settle into his new surroundings after joining for a fee that could reach £50million, with two goals in his 12 appearances not doing justice to a player whose combination of silky dribbling and teak-tough work ethic are ideal traits for Klopp.
“With Luis, where it has been really special is that when we saw him we knew that he would fit in immediately,” Klopp says of his latest recruit. “That is really difficult usually but because he did not have to change, that is why we have a really confident boy here."
But while Firmino may feel marginalised by the additions, he has instead continued to shape shift to find a new role within this Liverpool squad.
Six of his nine goals this season have come as a substitute with the other three arriving at Watford when he bagged a hat-trick in a 5-0 win at Vicarage Road in October. David Fairclough was known as Liverpool's 'super-sub' having netted 18 from the bench, but the Brazilian is up to a third of that this season alone.
And the man from Maceio has not embellished his and Liverpool's goal-return records by putting gloss on results from the bench, either. A number of his contributions have been decisive and game-changing.
Such as the glancing header in Milan to break the deadlock against Inter in the last 16 of the Champions League in February or the effort that took the game from Arsenal at the Emirates in that vital Premier League fixture earlier this month.
His strike at Norwich on the opening day against took the fight out of the hosts too as he made it 2-0 at Carrow Road before Salah sealed the victory later in the game.
With a little over a year left on his contract, what the future holds for Firmino is unclear at this stage, but his ability to readjust to whatever situation he is confronted with could yet be a handy characteristic for his Liverpool career.
