Liverpool boss Jurgen Klopp has a few selection posers ahead of their Premier League clash with West Ham - not least on the shape and tactical approach of his forward line.
Klopp used Mohamed Salah at the top of the attacking apex in their 1-0 win over Manchester City as the Egyptian's pace, and finishing prowess, saw him get in behind Pep Guardiola's side and score the game's decisive goal at Anfield.
It had been anticipated that £85m club record signing Darwin Nunez would take the central striking role in Klopp's new 4-2-3-1 system - but with the Uruguayan still finding his feet, and Salah's ruthlessness to the fore, there is a big call to be made on who should lead the line.
YOUR SHOUT: Tell us who should play in the central striking role for the Reds
Salah has nine goals and four assists from 14 games for the Reds in all competitions, while Nunez has four goals and one assist in 11 matches. But do numbers tell the whole story?
Then there is Roberto Firmino who operated centrally for Liverpool when 4-3-3 was Klopp's favoured formation. He has still managed to bag himself eight goals and three assists, albeit with some scratchy performances. Does he deserve to play up top ahead of the other two?
With Diogo Jota facing a long spell out on the sidelines will also come into the thinking of the Reds boss as he looks to manage the workloads of his forward players, so should Nunez get a longer run in the side in his favoured central position? Or does Salah's display against City mean it would be foolish to switch him wide?
