Salah 25 goals and 16 assists in 48 games
Firmino 21 goals and 8 assists in 49 games
Mane 14 gaols and 11 assists in 40 games
Origi 22 goals and 3 assists in 35 games.
Shaqiri, Ox and later in the season Everton chipped in with 20 goals and 17 assists between them.
As for the trickier games, mainly just dropping the defensive line and LOE sometimes and the LB role switched from F(s) to IWB(s) but mostly stayed as WB(s).
Didn't ever feel the need to change anything else, dropping the wingers to the midfield strata if a sending off or to sure things up.
