As the 2019/20 season draws ever closer and Fantasy Premier League managers step up their preparations, The Scout explains the FPL fundamentals.
While it is sensible to build a squad with a starting XI and formation in mind, managers must be flexible as the season progresses.
The 3-4-3 system is the most popular in FPL.
In that formation, the fifth midfielder and two benched defenders should be cheap back-up options for the first three to four Gameweeks.
But the value available in various positions can prompt a change of plan.
Last season, budget-friendly strikers were hugely successful.
Twelve forwards who cost no more than £7.0m at the start of 2018/19 went on to score 10 or more goals.
Raul Jimenez (£7.5m) and Callum Wilson (£8.0m) both started at £6.0m or under and totalled 181 points and 168 points respectively.
By comparison, in 2017/18 only two forwards who cost £7.0m or less at the start scored at least 10 goals.
If this trend continues, the improved output from reliable, budget-friendly forwards gives managers the option of investing more money in midfield.
This would allow them to pair big-hitters like Mohamed Salah (£12.5m) and Raheem Sterling (£12.0m) in a 3-5-2 formation.
By rotating two in-form strikers according to the fixtures, they can capitalise on the value available up front.
The goals and assists offered by wing-backs or attacking full-backs can also be a factor.
Defenders score six points for each goal in FPL, while midfielders earn five and forwards four.
Finding the players who offer a big attacking threat from the back can again lead to a change in tactics.
Andrew Robertson (£7.0m) and Virgil van Dijk (£6.5m) were among the top five highest-scoring players overall, totalling 213 and 208 points respectively.
And Trent Alexander-Arnold (£7.0m) produced 6.4 points per match, the third-highest average in FPL last season.
That kind of output can merit more investment in defence, with a switch to 4-4-2 or 4-3-3.
Reacting to on-pitch changes is also vital.
Diogo Jota (£6.5m) thrived after being moved up front for Wolverhampton Wanderers last season.
He did not score and only assisted one goal as a left winger in the opening 14 Gameweeks.
But after his switch to a more central role he scored nine goals and supplied seven assists in 20 subsequent appearances.
Monitoring such changes, as well as player form, will help shape and dictate your formation.
