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.
