As Fantasy Premier League managers can now select their 15-man squads, The Scout analyses standout budget and premium players in each position.
The stats show the influence and value attacking full-backs Robertson and Alexander-Arnold had in Liverpool's 4-3-3 formation in 2018/19.
Liverpool face only Arsenal and Chelsea of last season's top-six teams in their opening seven Gameweeks. So managers could look to spend on defence.
Robertson and Alexander-Arnold created 51 and 48 chances respectively last term. Only Mohamed Salah (£12.5m), with 68, created more for Jurgen Klopp's side.
The pair placed in the top-three defenders for chances created behind the 71 of Lucas Digne (£6.0m).
Robertson also became the first defender to break 200 points in FPL, producing 12 assists and 21 clean sheets to finish on 213 points.
That total placed the 25-year-old fourth overall in FPL in 2018/19.
Alexander-Arnold, meanwhile, finished as the third top-scoring defender despite starting only 27 Gameweeks.
He combined one goal and 13 assists with 16 clean sheets to total 185 points.
Indeed, his average of 6.4 points per match was ranked third overall among regular starters. Raheem Sterling (£12.0m) and Salah averaged more with 6.9 and 6.8 respectively.
Robertson and Alexander-Arnold may be the most expensive defenders in FPL but they still look cheap at a cost of £7.0m.

Liverpool's opening schedule furthers the case for doubling up on Robertson and Alexander-Arnold.
According to the Fixture Difficulty Rankings (FDR), five of their first seven opponents score only two.
That hands the Liverpool pair the chance to get points at both ends of the pitch, offering big value from the very start of the season.
